Abstract: An apparatus has a rotatable base having a plurality of guide features with opposed sides and supports. Each of the supports are slidably disposed in one of the plurality of guide features. The supports and the base member have spacer engagement surfaces which are configured to face one another in pairs and to have spacers clamped between each of the pairs. The spacers are so dimensioned as to locate each of the supports in a predetermined position with respect to an axis of rotation of the rotatable base member. A gear train on cut drive side is driven by a variable speed motor. Motor speed can be set for a given can diameter.

Abstract: An improved apparatus for trimming an irregular open end of a container body is disclosed. The improved trimmer cartridge includes a sealed gear housing, for retention of interior lubricant and to reduce contamination. An adjustment mechanism, accessible from the exterior of the housing, is provided to adjust a gap between two blades of the trimmer cartridge. The adjustment mechanism provides improved control over the gap width, which is between 8-25% of the can metal thickness. Additionally, a tang that is removably connected to a shaft for a first blade provides rotational power for the trimmer. The tang is replaceable without requiring the housing to be opened or requiring replacement of the blade shaft. Another blade shaft is provided for a second blade, with the two blade shafts having substantially equal mass. The trimmer also includes spur gears, which do not have the thrust load associated with prior art helical gears.

Abstract: The machining unit is composed mainly of three essential elements which are the rotor, the phase displacement device and the tool drive mechanism. The rotor (100) includes a rotating shaft (1) and is equipped, for example, with four bores, extending parallel to the axis of rotation, into which the cutter carrier axles (9a, 9b, 9c and 9d) are supported. A plunge of the cutters into the material to be machined is controlled by the movement of a command sleeve (19) supporting, at its end, two surfaces (20a and 20b) of ellipsoidal form located to move, in conjunction with the inclined surfaces (14a, 14b, 14c and 14d), the command levers of the tool carrier. The command sleeve can occupy two extreme positions and one intermediary position. A phase displacement device includes a pulley (22) and a reverse pulley (25) mounted rotatably on a shaft (31) to allow angular phase change of the command sleeve (19) with respect to the spindle.

The elongate frame rigidly supports the cutting blade support member and the shaft support member in opposed relation when the shaft is clamped therebetween.

Abstract: Relatively thick-walled (or solid) tubular members may be cut by a cutting tool which includes an annular frame having a rotatable ring which is adapted to surround the tubular member to be cut. A pair of cutting assemblies are radially connected to the rotatable ring of the annular frame so as to be orbitally movable about the tubular member to be cut in response to rotation of said rotatable ring. The radial cutting assemblies carry a bit subassembly (preferably a pair of generally radially opposed cutting assemblies) for cutting said tubular member. A drive/indexing assembly is provided so as to rotate the rotatable ring (and thereby cause the radial cutting assemblies to move orbitally about said tubular member), and indexing the bit radially toward a central longitudinal axis of the tubular member in response to orbital movement of the radial cutting assembly.

Abstract: A tube supported on a rotating mandrel is cut by a pair of cutter blades spaced apart a distance corresponding substantially to the diameter of the mandrel and which are moved simultaneously in a direction toward the mandrel and transversely of its axis of rotation a distance sufficient to enable the cutters to engage the tube at circumferentially spaced zones and sever the wall of the tube. The cutters move along a path that is tangential, rather than radial, relative to the mandrel.

Abstract: The pipe rotary cutting device of this invention comprises shifter means which is operative to rotate a cylindrical body relative to a main shaft to thereby rotate an internal gear secured to the cylindrical shaft. The rotation of the internal gear rotates pinion gears secured to the main shaft to thereby rotate eccentric shafts provided coaxially with the pinion gears. Then the rotation of the eccentric shafts is converted by sliders into radial movements. A cutting tool as well as disc cutters are provided on the sliders respectively through a cutting tool holder and cutter holders. The pipe rotary cutting device of such arrangement enables the steps of chamfering and cutting to be carried out simultaneously, and accordingly the chamfering step of removing the outward burrs created in cutting a pipe is totally unnecessary.

Abstract: The invention relates to methods and apparatus for making rings from tube stock (10) by a part-off rolling tool (12,15) which is advanced radially into the tube stock to form successive rings, e.g. annular blanks for subsequent roll forming into bearing rings. The tube stock is indexed forward after separation of each ring. Errors in the length of tube stock indexed forward each time are contained by forming a locating groove (47) on the tube stock by means of a groove-rolling tool (40) set at an appropriate axial distance from the part-off rolling tool (12) and moved radially with it. In the next cycle the groove (47) automatically centers the part-off tool as the latter begins its advance into the tube stock, so as to give the correct axial length of the finished ring. The part-off tool is stopped before fully penetrating the tube wall, which is then machined. Final separation takes place during this machining or in a subsequent finishing pass by the part-off tool.

Abstract: A can end trimmer has a main rotary support shaft with a radial turret plate. A plurality of self-contained cutter unit cartridge assemblies have radial head flanges directly connectable to one side of the turret plate with driven members in each cutter unit cartridge automatically engaging control members mounted on the turret plate for effecting movement of a transversely shiftable cutter knife into engagement with an axially fixed cutter knife for effecting rotation of both knives to trim the end from a can held in a vacuum chuck. A shim between the cutter unit cartridge and the turret plate cants the axes of the knife members with respect to the can by a very small amount normally less than 2.0 degrees to effect a smooth burr-free cut of the can end. Stripper pin means surrounds the can being cut which in turn surrounds the axially fixed knife with a reciprocating stripper plate on the pins being easily removed during replacement of the cutter cartridge unit.

Abstract: A device is provided which permits the simultaneous cutting or bisecting of a plurality of tires. Large, vertically mounted, circumferentially slotted wheels each adapted to receive a circular cutting blade in each slot, receive the tires. The cutting blades are mounted overhead on a shaft which traverses a pivotally mounted beam which is raised and lowered by a piston. A brake is provided for engaging the tread of the tire, and tensioning means engages the lower rim of the tire to exert a downward pressure when the overhead beam is lowered. Turning power is provided to the cutting blades by means of belts or chains which connect a motive source with the shaft on which the blades are mounted. Collars on either side of the cutting blades engage the tire tread when the blades are lowered to turn the tire. A plurality of slots and corresponding cutting blades can be provided for each wheel with spacers to determine the width of sections cut from the tire.
