A method and apparatus for aligning and transporting workpieces from a pickup location to a seaming location on a worksurface. Workpieces are rotated through a user-determinable seaming angle so as to re-position the workpiece for sewing a pure straight/angled seam at the seaming location. The device includes a self-compensation system wherein seaming of the workpiece will commence at the leading edge thereof regardless of the initial position of the workpiece at the pickup location.

Aligning device for sleeve

A method and apparatus for flipping and folding a pliable workpiece, such as a pre-hemmed sleeve blank, along a desired fold axis. A workpiece is conveyed past a flipping roller and down against a clamp bar wherein it is clamped at a predetermined time by a lower hem guide. The flipping roller is sped to impart linear momentum to the unclamped, trailing portion of the workpiece. The flipping action serves to re-orient the workpiece from a right side-up orientation to an inside-out orientation so as to properly present the workpiece for subsequent seaming or stitching operations. A sensor is provided to determine the length of the workpiece so as to enable the device to clamp the workpiece about any desired fold axis.

Sleeve flip over device

A hemmer seamer assembly comprising an apparatus for positioning a chain of stitches for stitching onto fabric having a needle and a throat plate, including a device for positioning the chain of stitches forwardly of the needle, and a device for moving the fabric to the throat plate for sewing the chain onto the fabric.

Hemmer seamer assembly

A method and apparatus is provided for transferring a batch of envelopes that have been arranged in face-to-face relationship. The envelopes are transferred in a substantially horizontal plane from a first location to a second location spaced from the first location. The apparatus includes a pair of downwardly depending spaced-apart members which are each adapted to contact the batch of envelopes along the end edges of the envelopes. One of the paddles is adapted to urge a batch along a guide channel from the first position to the second position. The other of the paddles is adapted to urge a batch along the guide channel in the opposite direction from the second position to the first position.

Method and apparatus for transferring envelopes

A method and apparatus is provided for feeding envelopes in a linear array between upstanding conveyor flights and for transferring the envelopes, a batch at a time, to an elevated position for removal to a next processing station. Envelopes are subsequently received in a receiving cradle at the elevated transfer station and are carried downwardly to a lower exit station where the batch of envelopes is discharged to a receiving bin.
