ABSTRACT:
A fabric-unwinding apparatus, wherein a travelling, body can move back and forth over a work table. A fabric roll is supported on a support table mounted on the travelling body, and an unwinding roll is set on the support table in a manner to be contacted and driven with the fabric roll. The support table is made to be horizontally swung through 180.degree. in both ways so as to take a first position where the unwinding roll lies in the forward part with respect to the fabric roll and a second position where the fabric roll lies in the forward part with respect to the unwinding roll. A fabric unfurled from its roll by the unwinding roll is suspended on a belt conveyer built below the unwinding roll and then transported by the belt conveyer to the forward part of the moving course of the travelling body. The transported fabric is set on the work table by the feed roll to be spread thereover. When the support table is horizontally swung through 180.degree., the front side of the fabric is kept upward instead of the backside thereof, thereby causing the front side of the cut pieces of the fabric placed on the work table to be kept upward instead of the backside thereof. The repetition of the horizontal 180.degree. swing of the support table causes the cut pieces of the fabric to be superposed on each other on the work table in such a manner that the front and back sides of the cut pieces of the fabric are alternately kept upward.
