ABSTRACT:
In order to mechanically prefabricate fitted elastic bedsheets of such dimensions that the manual work steps still required for completion of the fitted elastic bedsheets can be carried out efficiently in a short time, a device is provided which includes a first conveyor device for a strip of cloth, from which the individual fitted elastic bedsheets are cut. The first conveyor device intermittently draws lengths of the strip corresponding to the cut lengths of the fitted elastic bedsheets from a supply. A cutting device is provided at the end of the first conveyor device. At a right angle to first conveyor device is arranged a second device for the pieces of cloth which are cut by cutting device from strip of cloth. Stretched elastic bands are guided by feed devices along both lengthwise edges of the strip of cloth and along both cut edges of the pieces of cloth parallel to these edges in their stretched-out state against the strip of cloth or pieces of cloth, and finally are sewn tightly by sewing machines onto the strip of cloth or pieces of cloth. Sewing machines are positioned directly after the feed devices for the elastic strips. On each side of the second conveyor device are positioned additional cutting devices, which cut through the threads which still connect the individual pieces of cloth behind the sewing machines.
