Abstract: A method and a device for clampingly holding against a substrate (8), for example a drinking cup, a heat transfer sheet (5) using a clamping sheet (2), comprising providing a device (1) with a substrate holder (10) for clampingly holding the substrate (8); providing a clamping sheet (2) with a width and a length, length being measured between longitudinal ends of the clamping sheet (2), and wherein at the longitudinal ends of the clamping sheet (2) coupling means (3) are provided; and positioning in catch means (4) of a positioning device the coupling means (3) for keeping the clamping sheet (2) in a first position.

Abstract: A holding jig (1, 2, 3) for a thin cylindrical work (W) includes a holding member (10, 10A, 10B) which holds the work (W) from an inner peripheral side and a diameter changing unit (25, 27) which changes a diameter of the holding member (10, 10A, 10B). The holding member (10, 10A, 10B) is made of metal and has a cylindrical shape and an elastically expandable or contractible diameter. The holding member (10, 10A, 10B) is configured with an outside diameter of the holding member (10, 10A, 10B) being held smaller than an inside diameter of the work (W) at the time of insertion into an inner periphery of the work (W) and being expanded after inserted into the inner periphery of the work (W) to hold the work (W) from an inner peripheral side of the work (W) with an outer peripheral surface in close contact with an entire inner peripheral surface of the work (W).

Abstract: A workholding apparatus includes a body, and a workholding sleeve composed of metal and carried by the body. A fluid chamber receives a fluid between the body and the workholding sleeve. Under fluid pressure, the sleeve is radially displaceable and recoverable to a high degree. For example, when displaced under fluid pressure, the sleeve experiences substantially complete and repeatable strain recovery of at least about 2% of its overall cross-sectional area. Preferably, the sleeve is composed of Nitinol.

Abstract: This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.

Abstract: A workholding apparatus includes a body, and a workholding sleeve composed of metal and carried by the body. A fluid chamber receives a fluid between the body and the workholding sleeve. Under fluid pressure, the sleeve is radially displaceable and recoverable to a high degree. For example, the sleeve is radially displaceable to at least one percent in diameter with runout within about 0.03% of its diameter, and after release of fluid pressure repeatably recovers to within about 0.01% of its original relaxed diameter. In another example, when displaced under fluid pressure, the sleeve experiences substantially complete and repeatable strain recovery of at least about 2% of its overall cross-sectional area. Preferably, the sleeve is composed of Nitinol.

Abstract: The process provides an expandable chuck with a variable diameter bulb having a variable wall thickness, the chuck being operatively designed to stretch the bulb to reduce its diameter for insertion into a photoreceptor pipe and upon relaxation to the compress the bulb so as to increase its diameter. The design provides a universal chuck to reduce the cost of changing to different diameter chucks in accommodating different size photoreceptors during the coating and drying process.

Abstract: The invention pertains to a method and apparatus for clamping and subsequently machining a disk- or ring-shaped workpiece, wherein the workpiece is set down on a contact surface of a contact member made from elastomeric material. The workpiece is axially pressed against the contact surface with an elastomeric-material clamping member of a clamping device and simultaneously fixed in place perpendicular to the workpiece axis. Subsequently, the workpiece is machined with a tool.

Abstract: A clamping system for detachably assembling two pieces. The clamping system includes a clamping device concentrically mounted in a receiving section which extends in a hollow shaft of one of the two pieces, when the two pieces are engaged. The clamping system further includes at least two clamping bodies which can move in opposite directions and an actuating device which actuates the clamping bodies. The clamping bodies can be engaged with an undercut clamping shoulder of the hollow shaft and disengaged therefrom, whereby a pressure force is applied between the flat surfaces of the two pieces to be assembled.

Abstract: A circular flexible collet that provides a 360 degree gripping engagement with a cylindrical workpiece and which is operable by an actuator member incorporated in a workpiece chuck. The collet may be constructed as an internal collet for gripping engagement with a workpiece internal periphery, or as an external collet for gripping engagement with a workpiece external periphery. The flexible collet may be used for single, or plural workpiece gripping actions. The collet includes a split spring steel body having a radial opening split space and an outer and an inner circular periphery. One circular periphery is a workpiece gripping surface, and the other circular periphery has a tapered cam surface engageable by a workpiece chuck actuator member. The tapered cam surface has a plurality of circumferentially spaced apart slots, having an open outer end. In an internal collet the tapered cam surface is formed around the collet body inner periphery.
