ABSTRACT:
A cut segment of a strip of material is clamped intermediate its ends, prior to being cut, by two separate clamping elements. In one embodiment, one of the clamping elements is cammed towards the other clamping element as the clamping elements are moved to position the cut segment at a position for attachment to other material by a sewing machine, for example. This forms a loop or slack portion between the clamped portions of the cut segment so that attachment of the free ends of the cut segment produces a large loop when each end of the cut segment is attached to the other material. In another embodiment, one of the ends of the cut segment may be folded to form an overlapped portion for attachment to the other material so that a double thickness of the cut segment is attached to the other material. This embodiment still has one of the separate clamping elements movable towards the other to form a loop or slack portion between the clamped portions of the cut segment. In a further embodiment, each end of the cut segments can be folded to form an overlapped portion so that it can be attached with double thickness to the other material. In this embodiment, the two separate clamping elements remain fixed as to their distance between each other so that no loop or slack portion can be formed therebetween by camming one of the separate clamping elements towards the other.
