The present invention is therefore based on the task of creating a device and a method, around a stain made of a plastic material on one Surface part of certain oruses of a mass-produced article to be applied, the application of the piece being fyr suitable for mass production at low cost.

The above-mentioned object was achieved according to the invention by a process for applying a piece thermoplastic material on an object, preferably a screw, the pleck with a certain Part of.

Another part of the gate can be seen in the fact that the device makes it possible to odoi stains made of elastic thermoplastic materials on the screws "Manufacture other objects at a rate averaging over 600 objects per minute" This is a considerable advance in technology, particularly because the spots are essentially uniform in shape and size and ensure essentially uniform self-locking properties. Another advantage can be seen in the fact that excellent adhesion of the plastic material to the surface is guaranteed, which ensures sufficient torque both when used for the first time and when re-used.
