Patent ID: 8701938

Claim:
An applicator for extruding a semi-solid flowable material comprising: a nozzle assembly arranged to extrude at least one string of semi-solid flowable material, the nozzle assembly being mounted for rotation so that, by rotating, the nozzle assembly twists the string of semi-solid flowable material as the string is extruded; and a pump comprising a linearly movable piston for forcing, by its linear movement, said semi-solid flowable material through the nozzle assembly whereby the assembly extrudes the material; a pump drive mechanism connected to said pump for delivering a motive force to said piston; and a force-transmitting interconnection connecting said nozzle assembly and said pump, said interconnection being entirely mechanical, and transmitting said motive force through said pump to said nozzle assembly, said motive force causing said nozzle to rotate when a motive force is applied to the pump by said pump drive mechanism to operate the linearly movable piston.
