Abstract
A method and apparatus is provided for fusing tabs of a hook or loop fastener material to opposing ends of an elongated band of cooperating hook or loop fastener material. The tabs are fed from two sources of a first material on opposing sides of a bonding station. The band is formed from a supply of a second material which is first fed to a transfer device having first and second grippers. The grippers transfer the band of material to the bonding station in a direction transverse to the transfer of the tabs to the bonding station, and the ends of the band are placed in overlapping relationship with the tabs. Subsequently, a pair of ultrasonic welding horns are moved into contact with the overlapping material to fuse the band of material to the tabs. The apparatus operates under the control of a programmable controller and the length of the band may be varied by altering a length of the second material fed between the grippers of the transfer mechanism.
