Abstract: A rotary trimmer apparatus and signature trimming method are provided that enable operators to set a gap spacing between a rotating knife and an anvil at different predetermined sizes in an easy and accurate manner. The operator chooses the optimum knife/anvil spacing that produces a scissors-like cutting action on the particular type of signatures being trim cut and which does not cause premature knife dulling.

For this purpose, a user operated control assembly including a control knob and calibrated indexer are provided. To keep the knife/anvil spacing at the set size during trim cutting operations, a temperature control system is employed that keeps axial expansion of the knife spindle shaft from reducing the gap size.

Abstract: A saw having a self-pumped hydrodynamic blade guide or bearing for retaining the saw blade in a centered position in the saw kerf (width of cut made by the saw). The hydrodynamic blade guide or bearing utilizes pockets or grooves incorporated into the sides of the blade. The saw kerf in the workpiece provides the guide or bearing stator surface. Both sides of the blade entrain cutting fluid as the blade enters the kerf in the workpiece, and the trapped fluid provides pressure between the blade and the workpiece as an inverse function of the gap between the blade surface and the workpiece surface. If the blade wanders from the center of the kerf, then one gap will increase and one gap will decrease and the consequent pressure difference between the two sides of the blade will cause the blade to re-center itself in the kerf.

Abstract: A saw blade is stamped with a circumferential edge. At least one gullet and shoulder are formed in the circumferential edge. Likewise, a tooth pocket is formed in the circumferential edge. The tooth pocket is defined by a wall, generally radial to circle, on the shoulder, and a shelf substantially perpendicular to the wall. A tooth is secured, ordinarily by brazing, in the pocket such that a portion of the shelf extends beyond the front face of the tooth towards the gullet so that the tooth can be brazed along its entire lateral edge such that resultant forces in the tooth are transmitted to the body of the blade. After the tooth is positioned into the tooth pocket, the tooth, as well as a projection of the blade shoulder, are ground off so that the tooth and shoulder are flush with one another. Thus, the tooth longitudinal edge is in complete contact with the shoulder wall maximizing its strength.

Abstract: A cutter wheel which can form a deep slit on an article to be cut so that the article can be broken easily along the slit and a perpendicular cut surface can be formed reliably when the article is broken along the slit. The cutter wheel is a disk-shaped member having a cutting edge along the outer edge and formed with a mounting hole extending therethrough along its axis. The mounting hole has an irregular shape so that the cutter wheel vibrates when it rolls due to steps between adjacent sides of the polygonal hole. The edge of the wheel can thus penetrate more deeply into the glass plate so that a deeper and smoother slit can be formed in the glass plate. This in turn makes it possible to more easily break the glass plate along the slit and to form a perpendicular cut surface.
