Abstract
A pattern is applied to a travelling web, such as a rug, by delivering a carrier liquid with individually spaced apart quantities of a pattern liquid therein to the surface of the rug. The pattern liquid is delivered into or onto the carrier liquid via various types of applicator means and the individual quantities of pattern liquid are maintained in spaced apart relation at least until being deposited onto the nap of the rug.
Claims25
An apparatus for applying patterns to a planar structure, said apparatus comprising:
- first means for forming a transversely extending layer of carrier liquid;
- second means for transferring said layer of carrier liquid onto the surface of the planar structure in a transversely extending stream;
- and
- a dispensing means for adding a pattern liquid to said layer of carrier liquid in individually spaced apart quantities prior to transfer of said carrier liquid to the planar structure.
An apparatus for applying patterns to a planar structure, said apparatus comprising:
- a. an inclined run-off surface extending transversely towards and across a traveling web of the planar structure;
- b. means for delivering a layer of a carrier liquid onto an upper portion of said inclined run-off surface;
- c. a row of controllable valves for dispensing individual spaced quantities of a pattern liquid;
- and
- d. a further inclined run-off surface extending transversely towards and across said inclined run-off surface and under said valves to receive individual quantities of pattern liquid from said valves for transfer to said inclined run-off surface in individually spaced apart quantities prior to transfer of a stream of said carrier liquid from said inclined run-off surface to the planar structure.
An apparatus for applying patterns to a planar structure, said apparatus comprising:
- a. an inclined run-off surface extending transversely towards and across a traveling web of the planar structure;
- b. means for delivering a layer of carrier liquid to the upper portion of said inclined surface;
- c. a feeding device for delivering a further carrier liquid onto a lower portion of said run-off surface to introduce turbulence in the carrier liquid on said surface;
- and
- d. dispensing means for adding a pattern liquid to the layer of carrier liquid in individually spaced apart quantities prior to transfer of a stream of carrier liquid to the planar structure.
An apparatus for applying patterns to a planar structure, said apparatus comprising:
- a. an inclined run-off surface extending transversely towards and across a traveling web of the planar structure;
- b. means for delivering a layer of carrier liquid to the upper portion of said inclined surface;
- c. a transverse step at the lower end of said inclined surface defining a channel in said surface immediately upstream thereon;
- d. a feeding device for delivering a carrier liquid into said channel;
- and
- e. dispensing means for adding a pattern liquid to the layer of carrier liquid in individually spaced apart quantities prior to transfer of a stream of carrier liquid to the planar structure.
