Abstract: A paper discharging apparatus contains a movable mechanism and a control unit. The movable mechanism moves a surface part between a first position that the surface part is not contacted with a pinch roller and a second position that the surface part is contacted with the pinch roller through a paper so as to push the pinch roller; the control unit moves the surface part to the second position, clamps the paper by the pinch roller and the surface part, and conveys the paper, thereby bending the paper, and which moves the surface part to the first position and clamps the paper by the pinch roller and a feeding roller, and rotates the feeding roller, thereby discharging the paper from the conveyance path.
Abstract: An inventive apparatus for feeding rolled paper comprises rolled paper, a feed roller for feeding the rolled paper, a cutting unit for cutting the rolled paper, a driving source for actuating the feed roller and the cutting unit, a first gear train interposed between the driving source and the feed roller and a second gear train interposed between the driving source and the cutting unit. A reverse feed gear for transmitting driving force for a cutter gear to a feed gear is interposed between the first gear train and the second gear train and connects the first gear train with the second gear train when a movable cutter moves from a cutting position to a non-cutting position. Thereby, the feed roller is rotatively driven in the direction opposite to the feed direction by the driving force from the cutter gear.
Abstract: A method for perforating a sheet material provides for a perforating die located intermediate two orbital rollers. The two orbital rollers move in orbital paths in the same orbital direction at the same speed and in positions which are 180 degrees apart. Each roller acts as a temporary storage input and output in opposite phase from each other so that incoming sheet material is alternately stored and dispensed as a loop on the orbital roller. Since the rollers are out of phase, this permits a segment of the sheet material to be stopped intermediate the orbital rollers so that the perforating die can act on the stopped segment.
Abstract: Braided plastic sleeving useful in electronic applications is readily cut by means of a hot wire which is advanced through the sleeving when in flattened form at a controlled rate. It is important that the sleeving be under tension at the location where the cut is to be made. The size of the heated wire and the rate of advance of the heated wire through the flattened braided sleeving relative to the size of the braided sleeving is important to obtaining cutting and sealing of the ends of the braided sleeving without welding the ends shut. Means and method for achieving this is described herein.
Abstract: A strip cutting apparatus such as a photographic paper cutter senses position of the blade which cuts segments from the strip. The strip is driven in a reverse direction by a predetermined number of steps after the blade has cut the strip and before the blade is retracted. This back step motion or reverse motion eliminates the occurrence of interference between the forward edge of the strip and the blade as the blade is retracted. Damage to the forward edge of the strip caused by interference with the retracting blade is thereby avoided.
Abstract: The invention relates to automatic lines for cross cutting of coiled strips and is used to best advantage for cross cutting of coiled strips into plates intended for the manufacture of transformers.The automatic line of this invention comprises guillotine shears which are pivoted in the horizontal plane and intended to cut plates off a strip; non-pivoted guillotine shears intended to cut off sharp angles of said plates, said non-pivoted shears being mounted on a slider which is movable along the automatic line's axis in order to fix the non-pivoted shears at a desired distance from the pivoted shears in order to simultaneously cut off sharp angles and cut out plates; and a strip feeding mechanism being provided with only one pair of rollers driven by means of a reduction gear driven by a step electrohydraulic drive which feeds the strip, as well as accelerates, brakes and, if necessary, reverses the strip's motion to ensure a prescribed plate length.

Abstract: Apparatus for feeding a continuous web of photosensitive paper into a reprographic machine so that the leading edges of the paper and a transparent master sheet to be copied are co-incident as they enter exposure and developing stations, and to ensure that the tail end of the paper is cut, during continuous forward movement of the leading edge, so that the trailing edge of the severed paper co-incides with the tail end of the master sheet. The feed path of the paper includes a curved portion defined by an arcuate-section guide and a concentrically mounted roller. A loop of paper is formed by moving the roller out of the guide and the rear end of the paper is then held stationary and cut by a guillotine while the paper forming the loop is continuously fed forward. The timing of the feeding and cutting operations on the paper is controlled by micro-switches actuated by the leading and trailing ends of the master sheet.
