Process for the manufacture of fitted elastic bedsheets or similar seat covers

Abstract

In order to be able to execute the commercial production of fitted elastic bedsheets from a strip of cloth, markings are applied to the strip of cloth, which determine the attachment points for stretched elastic bands, the transverse cutting lines on the strip of cloth and the seams at the corners of each piece of cloth to be cut from the strip of cloth. The stretched elastic bands are sewn on or in the edges of the strip of cloth, while the strip of cloth is being moved in the lengthwise direction and is held in a flat state. Then individual pieces of cloth are cut from the strip of cloth. The stretched elastic bands then are sewn on or in the two edges of the pieces of cloth being moved transverse to the length of the strip of cloth, which corresponds to the cut edges. With this sewing process, the pieces of cloth are likewise held in a flat state. At this point, the piece of cloth is folded diagonally at each corner, so that the folded cloth segments lie one over the other and the corners adjacent to the edges of cloth pieces are flush. Then the folded cloth segments are sewn together at each corner of the piece of cloth along the markings for the seam and finally the folded cloth piece segments are cut off along each seam with cloth corners to the side. In the process, the stretched elastic bands can advantageously be automatically mechanically connected with the strip of cloth or the pieces of cloth which are already cut off. Thereafter the still required manual work steps are less time-consuming and can be executed simply at a manual sewing site.
