Abstract: There is provided a hydraulic shock absorption cutting and/or punching system which may be applied to a pre-existing press with said system having at least one damping cylinder that is under preset pressure supplied by a pump with the pressure chamber of the cylinder being connected with a damping valve. The damping valve has a piston-type displacing element including a throttle member, the construction and design of which provides for pressure-dependent adjustment of said throttle member in a housing on axial movement of said throttle member so that the cross section of a throttle gap is finely controlled and pressure-dependent adjustment of said gap is attained while also providing for practically constant flow through said throttle gap.

Abstract: An improved envelope opener comprising first, second and third shear stations for shearing three edges of an envelope in sequence one edge at a time. Each shear station sequentially aligns the envelope by contacting the edge to be sheared, shears the contacted edge, and then releases the envelope. Each shear station includes a self-sharpening and self-aligning anvil assembly comprising a pivotable anvil which is spring-urged to an adjustable home position. The home position of the anvil is adjusted by means of a rotatable eccentric stop. During a shearing operation, the anvil is pivoted away from and then back towards the home position. An overly thick envelope will keep the anvil pivoted away from the home position to avoid a jam condition at the shear station. A peel back station downstream of the last shear station peels back the top panel of the envelope to expose the contents thereof.

Abstract: A power tool, such as for example a bandsaw, incorporates a synthetic material moulding which is box shaped and mounts on the rear an electric motor and its housing, and on the front inside the box an implement drive mechanism such as a pulley in the case of the bandsaw. One side of the moulding mounts a switch actuating assembly substantially flush with the side by way of an OFF actuating plate pivotably received in a recess in the side and an ON actuating plate underneath the OFF actuating plate. In a preferred embodiment the opposite side to the one carrying the switch actuating assembly is adapted to rigidly support a structural metal spine member.

Abstract: An arrangement for notching or slotting circular blanks so as to produce stacks of rotor and/or stator laminations for electric machines. At least one slotting machine is provided which in a first direction is adjustable radially with respect to a spatially fixed axis of rotation of a blank support table by way of a separate adjusting drive. The support table for the blanks, constructed as an indexing apparatus, may be driven by a numerically controlled adjusting drive.

The stacks of lamination produced by the punching arrangement may include spiral slots or notches as well as oblique slots or notches enabling the production of special motors having a cone or tapered armature.

A roller is mounted on the base for movement along the blade. Means are provided for adjusting the pressure applied by the roller to the paper sample disposed between the blade and roller.

Abstract: Trim strip from a web slitter is received in a chute passageway which guides the trim strip away from the slitter. Low velocity air is supplied in the passageway to provide air lubrication between the chute structure and both opposite faces of the trim strip which thereby floats away from the slitter smoothly and efficiently.

Abstract: The tool positioner of a slitter scorer has tool engaging elements which are at least in part cylindrical and coaxial with a piston connected thereto. The cylindrical portion and piston are each independently guided by stationary guide surfaces in order to minimize bending forces on the piston.

Abstract: A flexible meat slicing blade and support therefor is provided for utilization in apparatus such as pizza forming machines to provide accurately and uniformly sliced meat products of specified thickness for deposit on a surface of a pizza shell. An elongated flexible meat slicing blade of this invention, which may be a continuous band, is supported for longitudinal movement in a cutting plane with the blade disposed at an angle with respect to that cutting plane. A cutting edge of the blade is beveled at an angle which is slightly less than the angle of inclination of the blade to the cutting plane. A support is provided for the portion of the blade passing through the cutting plane to maintain the flexible blade in precise position with respect to the cutting plane. This support includes a structurally rigid bar having a longitudinal groove in which the effective cutting portion of the blade is disposed for relative sliding movement.

Abstract: A machine for production shops to make templates, the machine including a flat base having stops against which a template blank can be rested two tracks going north to south, or vice-versa, along which a first gauge carriage travels ONLY north to south, or vice-versa, and which carries also two tracks moving east to west, in which a second gauge carriage travels; the second gauge carriage also carrying a precision telescopic punch aimed against the template blank.

Abstract: An improved flying cut-off machine is disclosed of the type in which a ram is supported for swinging movement induced by a ram actuating mechanism so as to operate a cut-off die set to cut off lengths from an elongated workpiece continuously emanating from a tubing mill. The improvement comprises the provision of an adjustment member included in the ram actuating mechanism which is interposed between connecting rod end members, one of which is pivotally connected to a motor driven crank and the other pivotally connected to the swinging ram. The adjustment member comprises a shaft having oppositely threaded ends threaded into the connecting rod ends so that a length adjustment can be made to the connecting rod, which in turn provides a simultaneous adjustability feature to both the vertical stroke and shut height of the ram produced by the crank rotation so as to adapt the apparatus to variously configured die sets having differing shut heights and strokes.

Abstract: In a shearing machine for a run-out roller table of a continuous casting plant, in particular a multiple-strand continuous casting plant for billets, including an upper and a lower cutter arranged in a shearing frame and movable towards and away from each other by means of drive and control aggregates. The shearing frame is mounted on a machine frame so as to be displaceable in the longitudinal direction of the run-out roller table. The shearing frame rests loosely on the machine frame, which machine frame exceeds the run-out roller table in height. The drive and control aggregates are mounted on the shearing frame and form a construction unit with it.

Abstract: An apparatus for cutting a blank sheet into strips and for stacking these strips in adjoining compartments separated by partitions is disclosed, the apparatus having circular blades mounted opposite each other in such a manner that they slightly overlap and are at an interval from each other in the axial direction on at least two shafts which can be rotated in opposite directions and are substantially one above the other, in order to cut the blank sheet fed between the circular blades and to feed the cut strips in the direction of the feed downward onto an inclined slide surface, which has, substantially on the same vertical longitudinal plane as the walls of the said adjacent compartments, guide walls the upper ends of which are preferably beveled and meet the inclined surface in order to receive the cut strips and to guide each of them into its respective compartment, lateral-transfer trays which extend, as seen in the direction of the feed, slightly forward and downward from the circular blades, are also i
