ABSTRACT:
An apparatus for working on limp sheet material has a support surface with a high coefficient of static friction relative to the limp sheet material. A sheet of low friction material is attached at one end to a carriage supported to move longitudinally of the support surface and is spread on the support surface by advancing the carriage. The limp sheet material is spread on the support material and shifted relative to the support material to align the sheet material in predetermined position relative to the apparatus. The carriage is retracted and the support material simultaneously withdrawn from between the limp sheet material and the support surface by winding the support material onto a pay-off/take-up roll. A brush and a roller carried by the carriage smooth wrinkles from the limp sheet material and press the material into engagement with the support surface as the carriage retracts.
