Abstract: Pattern printed textile products, such as pillow cases and items of apparel, are produced in such a manner that the pattern is always properly positioned on the final product. The pattern is printed on a fabric web while it moves in a first direction, and in synchronization with the pattern printing a magnetic mark is disposed (e.g. jet printed) on the web in a known position adjacent the pattern in the direction of fabric movement. A number of marks may be printed, which define the perimeter portions of the fabric if cut into fabric panels. Subsequently, the magnetic marking on the fabric is detected, the fabric is stopped, and rough cut is made at a known position with respect to the mark. A fine cut later severs the mark from the rest of the fabric. Automatic hemming can take place during fine cutting, and after fine cutting and hemming, other steps are performed to turn the fabric into a final textile product.

Abstract: A device and method for linearly inserting an interlining into the formation of a waistband of a garment such as slacks. The device has separate guiding means which directs different strips of fabric into a sewing mechanism which, in turn, combines the waistband components. One of the fabrics constitutes the interlining which prevents the waistband from rolling over in use. The guide for feeding the interlining into the sewing mechanism utilizes a linearly moving air cylinder. Pins on a holder pivotally connected to the cylinder attach to the interlining and feed it directly into the sewing mechnism. As a result, the pins and the interlining move linearly toward the sewing mechanism. As the cylinder returns to its starting position, the holder pivots to release the pins from the material to avoid pulling the interlining away from the sewing mechanism. Lastly, a knife connects to a second cylinder through a chain link.

Abstract: A fitted bed sheet and a method of making the sheet from a rectangular blank of sheet material are disclosed. Resiliently extensible strips having catches positioned at predetermined locations along the strips are enclosed within longitudinal, open-ended sheaths extending along opposite marginal edges of the blank. One end of each strip extends out of the open end of the sheath and the other end is anchored to the sheath. The blank is folded inwardly upon itself along fold lines to dispose the sheaths in a spaced apart, generally parallel relationship on the blank to form laterally opposed double-layered panels. Seams are then formed diagonally across the corners of the panels from adjacent the end of the sheaths to points along the fold lines so that a fitted sheet is formed. When the sheet is placed on a mattress, it is drawn into fitting engagement by pulling on the extended ends of the extensible strips and placing the catches over edges of the open ends of the sheaths.
