发明名称 Apparatus for fusing strips
摘要 Straps or belt loop strips are formed with the apparatus and method of the present invention by folding a strip of fabric about a strip of fusible material, threading the folded, combined strip back and forth between two side-by-side, counter-rotating cylinders so that, in the preferred embodiment, the strip forms a plurality of figure eight patterns over and between the two cylinders, and heating the cylinders to a temperature which is above the melting point of the fusible strip but below the scorching point of the material. The speed at which the cylinders are counter-rotated with respect to each other is chosen, in conjunction with the number of loops of the combined strip over the cylinders, to place the combined strip in contact with the heated surface for a length of time sufficient to accomplish complete fusing.
