The trap direction may include a choke, an overprinting, a spread, and/or a knockout.

The invention relates to a thread detector (F), especially for a thread sensor in a thread feeding device, comprising a detector foot (A) with an essentially flat rest (B) which can be brought into contact with a thread (Y).

As long as the key is inserted, a lifter engages with the detecting element from the rear.

The detector foot (A) has an uninterruptable surface (P) at least in the area of the rest (B) of said foot in order to gently handle the thread when swept and above all to prevent contaminants from attaching inside the detector foot (A).

The invention relates to a thread detector (F), especially for a thread sensor in a thread feeding device, comprising a detector foot (A) with an essentially flat rest (B) which can be brought into contact with a thread (Y).

The detecting element determines whether a key is inserted into the key channel of the cylinder core (10) or not.

The invention relates to a steering lock provided with an active connection possessing a detecting element in a radial recess (15) of a cylinder core (10).

For the dimensional verification Mollificio Valli has a MMC ZEISS multisensory machine which allows 3D measurements both with the optical technology and with a keyboard.
