Abstract: Apparatus for cross cutting and/or perforating of a web. The apparatus performs two consecutive partial cuts and, provides for positive guidance of a partially cut web. This is accomplished by first and second cutting blade rollers, arranged with one common counter cylinder and guided by groups of belts passing through breaks in the blades. The breaks of the two blades are laterally offset relative to each other, and the belts are pressed against the counter cylinder to convey the web. This eliminates the need for one counter cylinder and one pair of pull rollers, it decreases the danger of web tear and eliminates the web stretching and the accompanying offset of the two partial cuts.

Abstract: A hand-held jig for confining a bagel, or like object, while it is being sliced by a knife blade and a method of using the jig are disclosed. The jig comprises two identical structures that are joined together by a specialized hinge. The two structures are mirror images of each other and each comprises a circular cage (for loosely surrounding the rim of a bagel) that is attached to the hinge on one side and to a radially extending handle on the opposite side, and clamps in front of the cage for retaining and gripping the bagel and preventing its movement. The hinge is composed of material not injurious to a knife blade when it strikes the hinge, and is so constructed as to be fixed with respect to one of the structures and yet allow rotation of the other structure with respect to the hinge.

Abstract: A saw guide for use with a hand power saw comprising in combination a guiding platform with two generally planar edges which underlie or form two guiding edges for guiding the shoe plate of a hand power saw across a workpiece to make cuts at various angles, and two workpiece guide bars; one guide bar is generally stationary, engaging the end surface of a workpiece to initially align the guide; the other guide bar is slideable, engaging the opposite end surface of a workpiece. The sliding guide bar is releasably clamped in position. Both guide bars work in unison to hold the saw guide in relation to both workpiece edges, allowing the saw guide to slide along the top surface of a workpiece, but not swivel out of position. Two kerf gauges are slideably interlocked at both ends of the stationary guide bar. These gauges measure a cut line along both the top surface and edge surface of a workpiece. These gauges are easily swapped or replaced for use with different power saws, blades or blade tilts.
