Abstract (en)
A method of manufacturing weatherstripping includes tufting synthetic yarn into a primary backing fabric (32) to form tufts (46) on one side thereof and tuft "knuckles" on the other side. Then, the tuft knuckles are contacted with a heated surface (48) of controlled temperature to deform and flatten them, the combined thickness of the primary backing (32) and the tuft knuckles thus being reduced and the tufts (46) being more securely attached to the primary backing (32). Preferably, there is relative motion between the tuft knuckles and the heated surface (48) to effect a smearing of the tuft knuckles onto the primary backing (32). The flattened tuft knuckles may form a thin continuous strip adhering to the primary backing (32) and locking the tufts (46) thereto.
