  • Patent number: 4748922
    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.

  • Patent number: 4682555
    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.
