Abstract: Fabric-handling equipment which removes a fabric web from a stack of such webs or from a supporting surface, dries ink printed on a fabric, and removes a porous fabric held onto a surface by a vacuum. To remove a fabric web from a surface, like a stack of such webs, a device places needles partially into the web. Since the needles extend into the fabric less than about nine tenths of the fabric's thickness, they can only attach to the upper surface of a single web. The needles, after insertion into the web, separate from each other to effectuate a firm connection. When the device raises, it can only lift a single web. When a fabric web receives printing, touching it with a heated block having a Teflon surface cures the ink. This permits its subsequent printing or collecting and stacking. A fabric web may adhere to a supporting surface through suction.

Abstract: A single tray serves both as an intermediate tray, for temporarily stacking paper sheets between copying operations thereon when such paper sheets are copies plural times, and as a paper discharging tray for stacking paper sheets subjected to final copying. The tray is arranged on the upstream side of a paper resupplying device. The tray includes a first paper stacking portion and a second paper stacking portion separable from each other. A paper discharging device is provided with a branching guide arranged at an upstream side of a paper discharging location for branching a paper sheet of maximum size on which an image has been formed toward the tray and positioned so that a leading end of the paper sheet when housed in the tray will not reach a paper resupplying roller of the paper resupplying device.

Abstract: A compact machine architecture is realized by combining the functions of copy sheet feeding and stacking into one integral apparatus. The apparatus is initially completely filled with copy sheets to be moved into the transfer/fusing area of a copier/duplicator machine. A vertically translatable stacker tray is positioned above the copy sheet input and is moved downward in vertical synchronism with copy sheets being fed from the input stack. A paper feed roller, attached to the bottom of the tray, continually feeds the top sheet from the input supply. As the input sheet stack is consumed, the output (feed) copies are deposited onto the stacker tray. As operation continues the supply stack is depleted while the finished stack increases, but the overall volume occupied by the copy sheets remains the same. Since there is no "empty" volume in the apparatus, the size and cost of the unit is greatly reduced.

Abstract: In a recirculating feeder of sheets, the sheets are supplied and restored by the top-pick bottom-return method from a storing device in which the sheets are stacked and stored. The sheets are restored in the lowermost position in the stacking direction of the stacked sheets and stored in the storing device through a driving member, a first restoring device and a second restoring device. The driving member is controlled so as to approach/depart from the first restoring device, and when the sheet is conveyed into the storing device, it approaches to intervene between the lowermost position in the stacking direction of the sheets and the first restoring device, thereby pinching the sheet together with the first restoring device. In this way, the conveying force of the first restoring device is securely transmitted to the sheet, and repelling and mixing are avoided. The driving member contains defining members, which are intended to match the sheet stacking.
