Definitions

  • wide band saws for wood can be made with rows of teeth at both edges, cither for sawing in both directions, in which case all teeth are similar, or for smoothing the cut surface, in which case the rear teeth are smaller with mainly lateral cutting edges.
  • the latter type is also used for sawing abrasive wood where it might be necessary t o withdraw the saw if the cutting teeth have become dull, to avoid wood slivers obstructing the reverse motion.
  • the present invention concerns a bandsaw blade for the furniture industry, where the rear edge of the blade is designed to prevent and counteract any tendency to clog the cu t . while retaininc the fatinue resistance. 0
  • a bandsaw blade according to the invention is described with reference to figure 1. showing a lateral view of part of the blade.
  • the bandsaw blade has one longitudinal front edge with cutting teeth ( 1 1 ). one blade body ( 12) and one rear edge.
  • the rear edge comprises straight portions ( 13) and notches ( 14).
  • the teeth or their cutting tips ( 1 1 ) should preferably be made of harder ma t erial than the blade body (12). and could be made of carbide or high speed steel welded to the blade bodv bv known methods.
  • each notch should be short, with a longitudinal extent no longer than the average tooth pitch ( 1 5).
  • the radius of curvature should be larger than the depth of the notch and larger than the radius of the gullets between the teeth.
  • Each notch should be located opposite to a tooth so as not to cause a narrow section of the blade.
  • the distance between notches should be equal to the tooth pitch ( 1 5 ) or a multiple of it. less than thirty times the pitch.
  • a bandsaw blade according to the invention should be used wherever clogging of sawdust makes it difficult to withdraw a bandsaw from a cut. such as in furniture industry, wood milling industry, and manufacture of wood based boards, plastic laminates and soft metals.
