  • An adhesive applicator for applying adhesive to the side of the backing material sheet 14 that receives the elastic is generally indicated at 31.
  • the adhesive applicator 31 preferably sprays adhesive onto the backing material upstream of the conveyor dmm 28 to prevent accumulation of any possible overspray on the conveyor dmm 28.
  • the adhesive may be applied over the entire outward width of the backing material sheet 14 to provide adhesion for the sets of bands 20, 22 and pads 15.
  • a first nip roller 32a is mounted above the conveyor d m 28 for rotation about an axle 36a substantially parallel to drum axle 29.
  • the first nip roller counter-rotates relative to the conveyor d m in the direction indicated by arrow 33a and presses against dmm 28 at a first nip

  • the elastic used is 0.015 inch by 0.027 inch, three-strand natural mbber obtained from Fulflex.
  • the elastic may be any form of elasticized material which may be found to be desirable for producing the product at hand. Examples of other materials which might be used are polyurethane, ribbon elastic, lycra strands, or others used in the industry.
  • a splitter device which produces this function and also provides initial tensioning of the strands is indicated generally at 41.
  • This splitter device includes a first pair of powered counter-rotating rollers 42a between which the elastic strip 39b is moved.
  • a second set of powered counter-rotating rollers 42b are positioned downstream from rollers 42a with the elastic bands moving between the rollers 42b.
  • Rollers 42b are driven at a speed slightly higher than rollers 42a, such that the elastic band are stretched in tension.
  • a plurality of spaced pins 43 are disposed between rollers 42a, 42b with the elastic bands being routed about the pins to separate the elastic strip 39b into six individual bands.
  • an elastic feeder is positioned above the conveyor drum 28 and generally indicated at 44.
  • An elongate support member 48 extends from a frame 46 laterally across a machine centerline 51 that extends along the center of the dmm face 30 at the center of flow path 16.
  • a reciprocating belt 50 is trained about a pair of pulleys 52 which are rotatably mounted on the support member 48.
  • the pulleys 52 are positioned adjacent opposing sides of the flow path such that the belt 50 extends laterally across the flow path.
  • the belt thus has a first linear belt portion 51a positioned downstream of the pulleys and a second linear belt portion 51b positioned upstream of the pulleys. As the belt is moved about the pulleys 52, the first and second linear belt portions 51a, 51b move in opposing directions transversely of the flow path 16.
  • First and second feeder heads 53a, 53b are mounted on the belt for simultaneous, symmetric, reciprocative movement along a linear path 54 extending transversely of the flow path.
  • the first feeder head 53a is fixedly mounted to the first linear belt portion 51a at bracket 55a
  • the second feeder head 53b is fixedly mounted to the second linear belt portion 51b at bracket 55b.
  • the brackets 55a, 55b respectively include elongate extension members 56a, 56b that extend beneath the belt 50.
  • the feeder heads mount to the downstream ends of the extension members, and vertical guide flanges 68a, 68b extend upwardly from the upstream ends of the extension members.
  • the guide flanges 68a, 68b are slidably held within a grooved guide member 69 which extends parallel to the linear path 54.
  • the first and second feeder heads 53a, 53b move in opposing directions.
  • the sets of elastic bands 20, 22 are guided through the respective feeder heads 53a, 53b.
  • Applying the sets of elastic bands 20, 22 from the reciprocating feeder heads directly to the moving sheet of backing material 14 produces the symmetric curved elastic "hour glass" contour 21.
  • the first nip roller 32a has a relatively small diameter which is preferably about two inches.
  • the small first nip roller diameter permits the feeder heads 53a, 53b to be positioned very close to the first nip 34a to minimize "dragging" of the elastic bands as the feeder heads reciprocate along the linear path 54.
  • the short span of the elastic bands from the feeder heads to the first nip 34a permits precise application of the bands onto the materials 14, 17.
  • the shape of the elastic contour 21 is related to the ratio of the rate of lateral motion of the feeder head across the flow path 16 (feeder rate) and the rate of motion of the conveyor drum face 30 in the flow path direction 16 (conveyor rate).
  • the elastic is applied at a maximum angle relative to the flow path 16 when the feeder rate is at its maximum speed. Accordingly, the maximum feeder rate corresponds to the contour diagonal portion 26.
  • the elastic is applied parallel with the flow path when the feeder rate is zero, meaning the feeder head 53 is stationary.
  • the belt 50 is driven by a cam device 57.
  • the device includes a cam mounting plate 57a that is mounted on the frame 46 and supports a horizontally rotating cam 58.
  • the cam device 57 may be driven by a belt 62 and pulley 63a, 63b mechanism.

  • the belt 62 is trained about the pulleys 63 a, 63b to drive the cam 58.
  • the shape of the curved elastic contour 21 is varied by varying the shape of the cam
  • the cam is shaped in a 6th order polynomial curve to obtain the complex curved contour 21 shown in FIG. 1.
  • cam 58 is shown with a simple circular shape.
  • the preferred elastic contour 21 yields garments with leg elastic having varying selected curvature from front to rear about the garment leg openings.
  • any of a variety of elastic curves that are effective in retaining moisture may be produced through application of the cam mechanism.
  • an eccentrically mounted circular cam could be used, or the belt could be otherwise driven in a simple reciprocating fashion.
  • a connecting rod 64 extends from the cam device 57 to reciprocatively drive the belt 50.
  • the connecting rod 64 extends from a proximal pivot attachment 66a on the cam 58 to a distal pivot attachment 66b on a belt drive bracket 67 mounted to the second linear belt portion 51b.
  • Cam rotation reciprocates the belt to reciprocate the feeder heads 53a, 53b symmetrically along the linear path 54.
  • the tension in the elastic bands may be maintained at a substantially constant preferred level where the bands are applied to the first nip 34a. Maintaining a constant preferred level of tension avoids the tendency of the elastic bands to "bunch" together when the bands are applied in sharp curves on the material 14. Such bunching tends to occur due to excess variation in tension due to varying elastic band accelerations generated by the moving feeder heads in applying the bands in sha ⁇ curves.
  • a tensioning device may be provided along the elastic bands just upstream of the feeder heads 53a, 53b. Such a tensioning device varies the tension in the bands feeding into the feeder heads in order to counteract the variance in tension generated by the acceleration of the feeder heads in applying the curved elastic contours.
  • FIG. 2 shows a tensioning device 70 with a plurality of lower rollers 71a and upper rollers 71b through which the elastic bands are guided.
  • the upper rollers 71b are movable as shown in FIG. 2 to vary the tension in the elastic bands passing therethrough.
  • the upper roller movement may be controlled through a linkage 72a which is reciprocated by a cam 72b.
  • cam 72b the linkage 72a could be linked to cam 58 shown in FIG. 1 to appropriately control the upper roller movement.
  • the cam-controlled roller movement is correlated with the elastic tension generated by the movement of the feeder heads 53a, 53b along the linear path 54.
  • the upper rollers 71b may be moved toward the lower rollers 71a to decrease tension in the elastic when the feeder heads are accelerating along the linear path.
  • the upper rollers 71b may be moved away from the lower rollers 71a to increase the elastic tension when the feeder heads are stationary at either end of the linear path 54.
  • the tensioning device 70 is most effective when it is positioned as close as possible to the feeder heads 53a, 53b.
  • FIG. 3 shows another embodiment of a tensioning device 70b, which includes a belt 50b positioned over belt 50.
  • Belt 50 is illustrated in FIG. 1 and is covered by belt 50b in FIG. 3.
  • Elastic band guides 73a, 73b are mounted to belt 50b much like feeder heads 53a, 53b are mounted to belt 50.
  • the elastic bands 20a, 20b, 20c are guided through the band guides 73a, 73b just upstream of the feeder heads 53a, 53b.
  • Belt 50a is also reciprocatively driven (through cam 58 and connecting rod 64b) much like belt 50.
  • the belt 50b is linked to cam 58 so that the elastic guides 73a, 73b are reciprocated to maintain a generally constant tension in the elastic bands being fed from the feeder heads 53a, 53b.
  • the elastic band guides 73a, 73b accelerate the bands inward along the linear path to provide a preferred level of tension in the bands.
