Abstract: The present invention provides a wire feed device for guiding and straightening a wire which is comprised of a wire infeed unit and a self-cleaning deflection head which are connected together by a flexible guide hose. The wire infeed unit has a guide passage therethrough whose inlet and outlet are offset so the wire will remain in contact with a contact element within the passage to generate a signal when the wire is in the passage. The deflection head has a guide arc-shaped guide passage therethrough which, in turn, have outwardly radiating pockets spaced along the outer side thereof which remove debris (e.g. the material abraded from the wire and wire shavings) transport it out of the deflection head. Dimpled guide points are formed on the other side of the arc-shaped guide passage opposite the pockets to facilitate the self-cleaning of the wire. A wire straightening sleeve is positioned downstream of the deflection head, which can generate a control/monitoring signal is positioned downstream of the head.

Abstract: A spool for thread-type or strip-type wound material in a version for correct-sided insertion into a device, the spool on the one hand having a substantially cylindrical tube-type or cylindrical double tube-type winding core with flange disks of greater diameter arranged at its two ends for forming a winding area, and on the other hand being fittable inside the apparatus in a predetermined operating position with its central mounting bore arranged in the winding core and rotatable about its central axis. To obtain a spool that has on the one hand a simple and inexpensive structure and permits a simple, compact, and inexpensive configuration of the apparatus receiving the spool and on the other hand is versatile in use, i.e.
