(under subclass 102.1) Subject matter wherein one of the rigid members is rotatable for winding the sheet of cloth about this member, thereby enabling successive lengths of the sheet to be stretched.
(1) Note. Typically both rigid members are rotatably mounted, so that a length of sheet material is unwound from the first member (supply coil) which is then locked while the second member (take-up coil) is rotated to stretch the sheet material between the members.
