Abstract
This invention relates to a method and apparatus for reducing the sizes of the kerfs of safety belts made from severed webs of woven synthetic filaments such as polyamide or polyester filaments. In the preferred method, a laser beam sweeps across the belt to vaporize some of the belt material and severs the same. Preferably, all four sides of the belt are confined as by means of a clamping pressure to restrict the growth or expansion of the filaments in the direction outwardly of the sides of the belt. The preferred apparatus has means for feeding the webs to the severing station and means for actuating the clamp into clamping engagement to confine the belts as well as a discharge feed means for discharging the severed belts from the severing station.
