Claims
- 1. Apparatus for producing a product by adhesively securing yarn bits to an adhesive backing layer comprising pneumatic means for conveying yarn to a bit-applying station having a passageway extending from the source of yarn to said bit-applying station, means for supplying said adhesive backing to said bit-applying station, and means for severing yarn that extends longitudinally within the passageway, wherein the passageway comprises parts relatively movable to one another between a first relationship in which access is provided to the yarn for said severing means, and a second relationship in which the passageway is substantially continuous between its ends for conveying of said yarn, means to cause relative movement of said movable passageway parts to open and close said access; said bit-applying station further comprising a combination bit-applying and clamping means reciprocable to and from said backing layer between a position in which yarn is received from said passageway and a position in which said yarn is clamped against said backing layer, and wherein clearing means are provided to clear tufted yarn out of the path of the combination bit-applying and clamp means.
- 2. The apparatus according to claim 1 in which the severing means is adjustable parallel to the axis of the passageway to provide yarn bits of different lengths.
- 3. The apparatus according to claim 1 in which at least one of said passageway parts is flexible to accommodate relative movement of the parts.
- 4. The apparatus according to claim 1 in which at least one of said passageway parts is telescopic whereby to accommodate relative movement of the parts.
- 5. The apparatus according to claim 1 wherein the clearing means are associated with a tuft-retaining means adapted to hold said tufted yarn out of the path of the combination bit-applying and clamp means.
- 6. The apparatus according to claim 1 including backing layer guide structure to guide the backing layer through a directional change in the proximity of said bit-applying station.
