    Abstract: An apparatus for cutting an indefinite length suture strand to uniform lengths for subsequent threading and swaging to a surgical needle includes a drawing tower having at least one guide member defining a drawing axis parallel thereto. First and second gripping devices are provided to grip the indefinite length suture strand and draw it along the drawing axis; each gripping device mounted for reciprocal movement on at least one guide member. A retractable cutter for cutting the indefinite length suture strand is also provided for cutting the strand at a start position along the drawing axis. The indefinite length suture strand is fed to the drawing axis and drawn a predetermined distance beyond the location of the retractable cutter for positioning within a suture receiving opening formed in the surgical needle, while the second gripping device reciprocates to a start position along the drawing axis. The indefinite length suture strand is then inserted within the suture receiving opening of the needle and cut to a predetermined length by the retractable cutter after the second gripping means has gripped the indefinite length suture strand at the start position.

    Abstract: Apparatus for automatic coil feed of a sheet metal stock strip in progressive dies for punch press die operations which adjust the length of stock strip being intermittently fed to the punch press die while the press is operating. The apparatus comprises feed apparatus for feeding a predetermined length of stock strip to the punch press die which feed apparatus normally operates at a preset feed length. There is a control for maintaining the correct feed length of the stock strip being intermittently fed into the punch press die and includes a correction arrangement operable to mementarily change the preset feed length to supply a correcting length of stock strip to the punch press die. There are two longitudinal arrays of registration openings in the stock strip. A first probe mechanism operable when the stock strip stops to detect non-registration of a registration opening in one array resulting from overfeed of the stock strip and a second probe mechanism operable when the stock strip stops to detect non-registration of an opening in the other array resulting from underfeed of the stock strip. Upon detection of underfeed or overfeed of the stock strip, switches activate the control mechanism to shorten the length of stock strip fed to the punch press die or lengthen the length of stock strip fed to the punch press die as the detection case may be while the press is in an operating mode.

    Abstract: A selected length of a strip of material is intermittently fed past a cutting position having cutting means. The cutting means is activated only after a selected number greater than one of the selected lengths of the strip of material has been intermittently fed past the cutting position. The selected number of the selected length of the strip is variable so as to cut the same number of the selected length of the strip each time or to cut a varying number of the selected length of the strip in a sequential pattern. The selected length, which is fed during each intermittent feeding, also is variable.

    Abstract: The present invention is a strip feed control which is particularly useful in photographic systems such as film and paper cutters, film notchers, and printers. The photographic strip material is fed by a predetermined feed length during each operating cycle. The operator of the system visually monitors the position of the strip with respect to a reference position or indicator along the feed path and provides adjustment signal through an operator control knob. The strip position is moved in accordance with the desired adjustments, and the predetermined feed length for the next operating cycle is derived from the predetermined feed length of the just completed operating cycle, together with any adjustment in the strip position which was made by the operator.

    Abstract: A press including a supporting structure, a platen mounted on the supporting structure for movement relative thereto, and a cam drive for moving the platen toward and away from the stock to perform work operations on the stock. The cam drive includes a first cam for driving the platen up and a second cam for driving the platen down. Stock is fed to the press by a feed which includes two shuttles. The shuttles operate sequentially so that one shuttle moves through a feeding stroke while the other shuttle moves through a return stroke.
