Abstract
A novel slipper and its method of fabrication is described. The slipper comprises a substantially flat sole member with die-cut bounding edges onto which is heat-sealed an overlying arc-shaped vamp. The novel method is characterized by pre-tacking vamps at predetermined locations to a sole web, and substantially simultaneously heat-sealing each vamp to a sole and die-cutting the bonded sole and vamp from the sole web.
Claims9
A method of manufacturing slippers each having a flat sole member and an arc-shaped vamp disposed over the sole member to retain the slipper on the foot of a user, comprising the steps:
- a. providing a continuous sole web of sufficient lateral extent to enable plural sole members to be made therefrom,
- b. locating plural vamp sections over the sole web at predetermined locations,
- c. attaching the plural vamps in their final arc-shape to the sole web at the predetermined locations,
- d. positioning the sole web with preattached vamps under a sealing and cutting die, and
- e. heat-sealing the preattached vamps at opposite sealing zones to the sole web by the sealing die and substantially simultaneously die-cutting entire slippers with heat-sealed vamps from the sole web.
