摘要:
At both ends of glass cloth comprising warp yarns consisting of a number of glass monofilaments and weft yarns consisting of a number of glass monofilaments, the weft yarns being cut at the ends of the glass cloth, glass monofilament-fixing portions are formed by fusing the ends of the weft yarns, by substituting a synthetic resin yarn for the warp yarn at the end of the glass cloth and melting the synthetic resin yarn or by attaching an adhesive tape to the ends of the glass cloth. The glass cloth having the glass monofilament-fixing portions at both ends thereof is advantageous in that no broken pieces of glass monofilament were formed when preparing prepreg or laminate using the glass cloth, and the laminate has excellent accuracy of thickness.

A predetermined or sensed length of fabric, such as toweling, is delivered to a position between fixed and movable devices having parts which, upon engaging the fabric, have the capability of forming and folding it to produce conventional hems. The fabric is severed between hem portions so that one hem is developed on the trailing end of one article while simultaneously a second hem is developed on the leading end of the next article. A part of the folding means also has the capability of depositing adhesive within the second fold of each hem to secure the hem without stitching after the application of pressure.
