Device and method for embedding threads in a rubber profiled element

A device for embedding a thread in a rubber profiled element in a given direction comprising:

• a continuous thread-feed means arranged on a fixed structure;
• a moving support able to run along a structure in a reciprocating rectilinear movement between a raised position and a lowered position and comprising a top and a base between which is formed a duct intended to guide the thread;
• a hollow needle comprising a canal in which the said thread is able to run, which needle is fixed by one of its ends to the base of the moving support in the continuation of the duct, and comprising at its other end a tip capable of penetrating the said rubber profiled element;
• and
• a cutting means arranged on the structure, comprising a rotary blade comprising a cutting portion able, when the needle is in the raised position, to cut off the thread at a given distance from the tip of the needle upon each cycle of reciprocating movement of the needle and to produce a tail of thread extending from the tip of the needle,
• wherein the cutting means comprises a paddle arranged behind the cutting portion of the blade and intended to fold the tail around the tip of the needle just after the thread has been cut by the blade.
