Abstract: A method for producing a mini chip card out of a standard card having an embedded semiconductor chip uses a punching die with cutting edges defining the outer contour of the mini chip card. The punching die is adjusted relative to the standard card and with respect to contact surfaces of the embedded semiconductor chip so that the edges of the punching die are at a predetermined distance from the contact surfaces. The punching of the standard card is performed in this adjusted position so that the contact surfaces are in a reference position with respect to the outer contour of the mini chip card. The punching forms the mini chip card in the correct position in the standard card. The mini chip card may initially remain connected to the standard card by thin bars between the cards.

Abstract: A dispenser for sequentially dispensing web material from a primary web roll and then a reserve web roll. The dispenser senses the presence of the primary web directly at the feed nip defined by two feed rollers and introduces the leading edge of the reserve web roll to the feed nip immediately after the trailing end of the primary web roll passes through the feed nip. The movement of one feed roller relative to the other feed roller actuates the transfer mechanism which introduces the reserve web to the feed nip.

The sleeve member is slidably movable relative to the spline shaft in an axial direction of the slide shaft, and the rotational position of the sleeve member is fixed relative to the slide shaft around an axis of the spline shaft. First and second covers are disposed around the slide shaft on opposite sides of the sleeve member forming first and second air chambers in communication with each other.

Abstract: A punch press having a rear address configuration is described in which a forward facing carriage cross slide is mounted within the throat space of a punch press main frame and an auxiliary turret frame mounts the punch and die rotary turrets separately from the main punch frame, avoiding the need to prevent turret misalignment by main frame deflection during punching. Separate turret modules also allow matching different turret configurations to various punch press configurations. A turret module having different diameter independently driven upper and lower turrets is also disclosed, allowing a greater number of dies than punches to be stored to allow any several dies to be mated with a particular punch for proper punching with various materials.

Abstract: The machine cuts a roll or log (L) of web material into a plurality of small rolls (R). It includes a unit (17) rotating about an axis (A--A) parallel to the axis of the log (L) to be cut. The unit carries a cutting blade (19) rotating about an axis (B--B) parallel to the axis (A--A) of the unit (17). A driving device (61, 63) moves the cutting tool (19) into a reciprocating forward and backward motion parallel to the axis of the log (L) to be cut. At least at the time when the blade cuts the log, the blade moves parallel to the moving log at a translation speed substantially equal to the feeding speed of the log (L), so as to allow the cutting of small rolls (R) without stopping the log (L).

Abstract: An apparatus for forming a spread of generally thin, pliable material from a roll thereof onto a table includes a cradle for holding the roll of the material which is selectively operable to rotate the roll of material for feeding a web of material generally forwardly from the roll. An endless conveyor including a series of flights spaced at intervals therealong with openings between the flights is driven for forward travel, and the web from the roll of the material is received on and carried forward by a flight in the upper reach of the conveyor. A knife is operable to cut the web to separate a first sheet of material from the roll of material. The first sheet of material is thereafter held from forward movement with the supporting flight by grippers selectively operable for gripping the first sheet of material on the supporting flight in the upper reach of the conveyor. Thus, the supporting flight slides out from under the first sheet of material with the first sheet falling onto the table.

Abstract: An arrangement for cutting stacked sheets of material resting on a bench. A hydraulically actuated holdfast beam descends onto the material to be cut, and the cutter travels perpendicular to the surface of the bench adjacent to the holdfast beam. A sensor operates during the cutting in conjunction with a circuit that controls the holdfast beam, and emits a signal to reduce the beam's holdfast force. The sensor is mounted below the holdfast beam and outside its effective surface that comes into contact with the material being cut. The distance between the sensor and the effective surface of the holdfast beam equals the distance between a lower edge of the holdfast beam and an upper edge of the stacked material that is being cut.

Abstract: An arrangement for optimizing the unproductive motions of a holdfast-beam in a machine that cuts sheets of material that are stacked on a bench. A hydraulic beam descends onto the stack of sheets to hold them fast before they are cut, and rises again after the sheets have been cut. A definite distance between the holdfast-beam and the material that has been cut is determined while the beam rises off the sheets of material. The rise of the holdfast-beam is terminated when a definite distance is determined.

Abstract: An improved paper towel and toilet paper portable dispenser is provided, which consists of a housing having a cylindrical body, a pair of end walls and a longitudinal flap between the end walls, to provide an opening in the cylindrical body of the housing. Components are for rotatively retaining a roll of paper toweling/toilet tissues within the cylindrical body of the housing between the pair of end walls, so that a free portion of the roll can extend through the opening in the cylindrical body of the housing. A serrated cutting blade is along an edge of the opening in the cylindrical body of the housing for tearing off the free portion of the roll, so that a person can utilize the free portion. A strap is affixed to one of the retaining components for carrying the dispenser.

Abstract: A method for optimizing the cutting of sheets of material that are stacked on a bench in a cutting machine. Before cutting the sheets, a beam descends to hold the sheets fast while guillotine blade descends and cuts the sheets. After the sheets have been cut, the blade and beam are lifted, with the lower edge of the beam following the sharp edge of the blade. A definite distance between the blade and the top of the stack is determined while the blade rises after cutting the sheets. The rise of the blade is terminated at the upper end of that distance, which is determined by a pick-up mounted stationary on the holdfast beam. This pick-up detects the position of the rising blade in relation to the holdfast beam.
