Definitions

  • the present invention relates to a shears construction for cutting a web of material, for example, for severing from a web of material, wrappers for a packaging machine.
  • the stationary blade is held between linear contact clamping means at each of the two ends only.
  • FIG. 1 is a diagrammatic side view of the stationary blade of the shears construction
  • FIG. 2 is a vertical section taken on the line II-II in FIG. 1.
  • the stationary blade 1 which cooperates with the movable blade 2, rests at each of its ends with linear contact on a support 3 of the frame 4, and is clamped on the support 3 by the cylindrical head 5 of the bolt 6, the said head extending at a right angle to the body of the bolt and to the cutting edge of the blade.
  • the support 3 is formed with an upper surface having two slopes intersecting to form a ridge.
  • a frame having spaced supports with each of said supports having sloping surfaces meeting in a ridge and a blade affixed to each of said supports by a bolt, each of the bolts having a cylindrical head disposed perpendicular to its shank with the longitudinal central axis of each of the cylindrical heads being disposed in the same vertical plane as the ridge of each of said supports and transverse to a cutting edge of said blade, whereby said blade engages said frame only by the linear contact of a face of said blade with the ridge of said supports.
  • a shears construction for cutting a web of material comprising a frame having spaced supports with each of said supports having sloping surfaces meeting in a ridge, a first blade afiixed to each of said supports by a bolt, and a second blade mounted for movement into temporary contact with said first blade, each of the bolts having a cylindrical head disposed perpendicular to its shank with the longitudinal central axis of each of the cylindrical heads being disposed in the same vertical plane as the ridge of each of said supports and transverse to a cutting edge of said first blade, whereby said first blade engages said frame only by the linear contact of a face of said first blade with the ridge of each of said supports.
