Abstract: An apparatus and method for manufacture of carpet is disclosed where yarn bits are forced onto an adhesive covered backing. Yarn is moved through an outlet and severed after application to the backing. Also disclosed is a yarn feed device and a multicolor carpet printer.

Abstract: A program controlled multiple stream liquid application process in which longitudinal asynchronism between the application of the portions of liquid is reduced by intermittently or continuously detecting the emission of a test stream at each liquid application station, generating, in response to said detection, an electrical signal indicating the time of emission of each test stream with one or more reference times and thereby to generate a correction signal indicative of the extent of longitudinal asynchronism, and modifying the program control in response to the correction signal. A complementary apparatus is also disclosed. In a separate aspect, multiple stream liquid application apparatus includes means coupling the conveyor and the liquid applicator means so that lateral displacement of the conveyor induces a corresponding displacement of the liquid applicator means.

Abstract: Apparatus for applying liquid to a moving strip includes a conveyor, a reservoir for the liquid, an array of multiple nozzles arranged above and transversely of the conveyor, and multiple remote controllable valves actuable by a programmable electronic control to cause respective streams of liquid received from said reservoir to issue from the nozzles onto the strip in accordance with a predetermined pattern. A multiplicity of fluid distributors are provided between the valves and the nozzles so that one or more repeats of the pattern occur across the strip. The lengths of the fluid lines connecting the nozzles of each group to its distributor are substantially equal. Novel fluid distributor construction are also disclosed.
