Abstract: A folding machine for processing printed sheets has a folding pocket into which sheets are fed by a pair of rollers. The infeed of the folding pocket has a guide plate and a guide device between which sheets are guidingly fed into the pocket. The guide device consists of a succession of several profiled segments releasibly secured to a carrier, preferably slidingly mounted in a groove in a carrier by means of clamping screws. The profiled segments may be spaced from one another so as not to contact adhesive strips on the sheets. Because guide device consists of several segments, the spaces between segments can easily be varied to match sheets having different formats of adhesive strips.

Abstract: A bag machine includes a programmed logic controller intermittently actuating a web feed draw roll motor for controlled web feed during the inoperative period of a cycled seal bar. The controller has separate inputs for the seal bar periods and a web length and establishes a control program of a preferred motion profile, with acceleration and deceleration of the fixed rolls to match the bag length to the available time using the total time available, with acceleration to a maximum and deceleration to reference, with or without a constant speed period. The bag length and time is monitored each machine cycle to calculate the next motion profile and permit changes in the bag length without machine shut-down. A programmed registered mode of control responds to a web mark spacing relative to the seal bar. In the registered mode, a photoscanner detects the mark during a constant speed web feed period prior to the end of the available time and actuates the web feed accordingly.

Abstract: By rotating at a high speed a cutter wheel having air intake ports and air injection ports which communicate through an inner cavity, surrounding air is introduced into the cavity from the air intake ports and discharged out through the air injection ports by the centrifugal force brought about by the rotation of the cutter wheel, to spontaneously induce a strong current of air. In this manner, cutting bits which are attached to the peripheral portion of the cutter wheel and produce superheat in cutting a rigid material such as concrete are effectively cooled by the air current thus induced.

Abstract: The invention relates to a cutting tool, particularly a carving insert or cutter bit, which is exchangeable in tool holders in each case has a cutting wedge, which is adjacent to a face, one or several nubs in the form of spherical segments, truncated cones and/or truncated pyramids being formed on the face.

Abstract: This application discloses an improvement for a conventional open-end adjustable wrench comprising a recess in the movable jaw of the wrench adapted to receive the first end of a chain. Spring biasing means on the first end of the chain to releasably retain the first end of the chain in the recess and a curved lip on the fixed jaw adapted to receive and retain the opposite second end of the chain are also disclosed. Finally, a ratchet-like motion achieved by the modified wrench is disclosed wherein the work object is engaged in a non-slip manner during the movement of the wrench handle in one direction, and in a slipping manner during the movement of the wrench handle in the opposite direction. The unique refined feature of maximum adjustment provided by the flexible movement of the wrench jaw being repositioned where the knurl is moved allows the full ratchet-like action motion to be applied to the work object.

Abstract: Flexible drapable sheets, such as cloth sheets or garments, are folded and stacked. A first horizontal conveyor conveys the garments past an automatic sewing machine to a lifting device which engages a middle portion of the garment and stuffs it into the inlet of a vertical second conveyor formed from two sets of horizontally spaced conveyor tapes. At a discharge end of the second conveyor, the garments are discharged onto a receiving surface formed by a number of bent wire sections interleaved with the conveyor tapes of the second conveyor. The receiving surface is flipped over (pivoted about a horizontal axis) to flip the folded over garment onto a platform above the first conveyor. The garments are stacked to a desired height on the platform.

Abstract: A seal assembly is mounted within a grinding machine to separate a grinding wheel from the main portions of a wafer being ground. The seal assembly has a pair of free edges which are disposed to define a V-shaped gap through which the peripheral edge of the wafer passes into grinding relation with the grinding wheel. A perforated hollow tube is also mounted behind the free edges of the strips to blow air onto and across the planar surface of the wafer being ground to prevent accumulation of debris thereon.

Abstract: A coaxial cable stripping tool has a pair of opposing jaws which include a stripping jaw and a clamping jaw supported as associated ends of a pair of pivotally moveable operating handles. The stripping jaw has a pair of spaced apart cutting and stripping blades for cutting axially spaced portions of a cable to be stripped when the cable is gripped by the jaws and the tool is rotated about the axis of the cable. The jaws are normally spring biased to closed position and move to open position in response to operation of the handles. A clean-out member mounted on one of the handles sweeps through the space between the blades to dislodge scrap material trapped between the blades each time the handles are operated to open the jaws.

Abstract: In twin-chamber compressed gas packs, the collar of a diaphragm which invaginates during motion in the container is secured with its opening region in a fold or in the upper part of the container, in order to provide the required sealing between product chamber and working fluid chamber. The disadvantage of packs of this type is that the use of multipart containers is mandatory and/or that a support ring incorporated in the diaphragm produces a frictional force which may be large enough to prevent ejection of the feed material because of an insufficient pressure differential between the chambers. These drawbacks are overcome by securing the entire region of the collar to the internal wall of the casing.

Abstract: An improved cutter disk for machining rotating workpieces, and in particular an improvement in such cutters useful in monotonic-type cutters in which the tool inserts carried on the disk are mounted in such a manner as to present the inserts to the workpiece at a radical lead angle, optimally on the order of 60 degrees. The tool inserts are preferably carried on both sides of a V-shaped edge on the cutter disk. Chip gullets are formed in the disk parallel to the tool inserts and are angled with respect to the plane of the disk. This optimizes the space for chip gullets and allows either a doubling of the feed rate for a given chip thickness and insert density, or a reduction in chip thickness by 50% for a given feed rate. The invention also results in the optimal use of space for the chosen insert density, especially on narrow cutters, and permits an improvement in the pocket strength and insert strength, as well as improving tool life.
