  • Transporting limp fabric
    Patent number: 4905983
    Abstract: A method and apparatus for transferring a limp fabric piece (6) wherein the fabric piece (6) is deposited on a low frictional plate (7) supported by a movable carriage (not shown) mounted on wheels (10). The carriage is then moved to a position beneath a frictional gripping device (9) which is then lowered onto the fabric piece (6). The carriage with the low friction plate (7) is then withdrawn from beneath the gripping device (9) and returned to its original position leaving gripping device (9) in frictional engagement with fabric piece (6).
    Type: Grant

  • Method and apparatus of separating and transporting fabric pieces
    Patent number: 4712782
    Abstract: A method and apparatus for transferring single pieces from a stack (16) of limp fabric pieces to a receptor (25) for further processing wherein a drum (10) is brought into pressure contact with the top piece in said stack (16) and a marginal portion of that fabric piece is gripped by the drum (10) via a friction roller (20) carried by the drum. The drum (10) is then rolled over the stack (16) so the top fabric piece to be wrapped about the periphery of the drum (10). The drum (10) is then transported to an operative position above the receptor (20) and rolled thereover to lay the fabric piece flat on the receptor (25).

  • Transport and guide for sewing limp fabric
    Patent number: 4686916
    Abstract: A method of sewing along a marginal edge of a fabric piece wherein the fabric piece in a flat state is gripped between a stationary low friction surface and a movable high friction surface, so that movement of the high friction surface relative to the low friction surface will slide the fabric piece over the low friction surface, while maintained in the flat state. The fabric piece is gripped so that the marginal portion to be sewn is exposed, and as the fabric piece is moved over the low friction surface the marginal portion of the fabric piece is moved along a path through a sewing machine head so a sewing operation may be performed thereon.
