Abstract: A battery case is made by cutting from a blank case of a bottomed cylindrical battery case having an unwanted portion at an opening portion the unwanted portion from the case wall in the circumferential direction by a blade. The cutting of the case wall is performed so as to render a cutting-end portion higher than a cutting-start portion. Thus, re-cutting of the cutting-start portion by the blade after it has already completed one rotation can be avoided. As a result, the generation of thread-like chips from re-cutting of the cut surface can be avoided.

Abstract: An apparatus for cutting hollow, metal, spirally formed pipes is disclosed. The apparatus uses two passive, rotatable knife blades to cut the pipe. An upper knife blade is positioned inside the pipe so that its cutting edge is adjacent to the inner pipe surface. A lower knife blade is positioned outside of the pipe so that its cutting edge is adjacent to the cutting edge of the upper knife blade in the lateral direction, but is clear of the pipe and upper knife blade in the longitudinal direction. To cut the pipe the lower knife blade is raised until its cutting edge overlaps the cutting edge of the upper knife blade. The knife blades then puncture the pipe. The pipe is rotated through the overlapping blades to completely cut the pipe. Since the pipe moves spirally (i.e., it moves forward while it rotates), the knife blades are adapted to move in the direction of the pipe during the cutting process. This permits the overlapping knife blades to cut the pipe rectangularly.

Abstract: This invention envolves a columnar material cutting machine which has a stationary cutter fastened into a base and having an inner opening substantially equal to the outer profile of a material to be cut, a movable cutter contacted at one end therewith with one end of the stationary cutter and having an inner opening substantially equal to the shape as the stationary cutter, and drive means for moving the movable cutter in a circular motion without rotating the movable cutter. Thus, the machine can cut a solid columnar metal or a metal pipe with a smooth cutting surface without cutting chips.

The apparatus may also include a tire support for holding the tire in a horizontal plane while removing a tire bead.

Abstract: When trimming a pressed disc record it is desirable that the central hole is concentric with the trimmed edge. Hitherto the central hole or marker produced at the pressing stage has been engaged on transfer while the record is still held in a transfer means to force the record into position for trimming. The invention provides that the record is first transferred and then centralized at the trimming position, while freely movable, e.g. by inserting a taper through the central hole to move the record to the center of the trimmer. Damage to the central hole is thus reduced.

The other one of said cutters is made in the form of a ring consisting of two half-rings, the longitudinal axis of said ring being coaxial with the axis of the inner surface of the hollow holder at the moment of receiving the bellows to be cut-off. The half-rings are adapted for closing radially when clamping the bellows and for opening when releasing the bellows after its throat has been cut-off.

Abstract: A method of orbital shearing of elongated stock such as tube stock comprises passing the stock through aligned dies, then causing relative lateral displacement, arcuate or linear, between the axes of dies, and causing a relative orbital movement between one die and the stock held in the other die. The lateral movement causes partial shearing, which is propagated around the stock by the orbital movement. One die may be fixed, while the other performs both the lateral and then the orbital movement. The stock may be rotated, in which case the moving die only has to move laterally to achieve the orbital movement as well.
