To form a yarn reserve winding on a cross-wound bobbin, pref. at the head end using the doffer, a pre-set yarn length is used as the reserve, which is unwound from the bobbin to be held for itnermediate storage. A sensor registers that the yarn reserve length is present in the store. When the required length has been unwound, the bobbin is stopped and its rotation is reversed back into the winding...

A liquid painting instrument according to the present invention includes a neck portion of a cross-sectionally noncircular configuration provided on a wall having a passage hole that allows the neck member of the inner shaft to pass therethrough at a certain position in a circumferential phase while preventing the neck member from passing therethrough at other positions in the circumferential phas...

A liquid applicator according to the present invention includes an inner shaft as a liquid reservoir, an applying member, and a valve, wherein near the front end of the inner shaft there is provided a head portion which is non-circular in cross-section along the direction perpendicular to the axial line. At a position in front of the head portion of the inner shaft in an unknocked state, there is ...

In a self-locking belt roller, especially for motor vehicles, having a vehicle-sensitive and/or belt-sensitive control system for its locking element, which in the blocking case prevents further rotation of the belt winding shaft, and having a winding-up spring acting on the belt winding shaft, in certain operational conditions the blocking system of the belt roller should be permanently ready to ...

A method of making sealing ring, for use in valves includes producing a cylindrical pressed cup from a film, and then slicing the cup in a direction normal to its longitudinal axis.

The module insert is fitted with a front panel (10) which incorporates a number of recesses (20, 21) in its front face, used to house LED or potentiometer devices, inserted before fitting a front indication plate to the front panel (10).

In a control cam running on the sliding face of an actuating member for a gas-exchange valve of a reciprocating engine, with a first cam sliding face 6 comprising a run-on and a run-off flank and with a second cam sliding face 5a, 5b comprising the base circle, one of the two cam sliding faces is equipped with a recess 4 and to achieve a reduction of the abrasive wear, especially the wear of the s...

A device for removing air or water from vehicle parts has a channel 1, in the free cross-section of which there extend, starting from the walls, helically continuous projecting webs 2. The helically arranged webs or lamellae serve for preventing the transmission of sound from outside. To inhibit this transmission of sound in an especially effective way, the pitch of the helix is selected as non-un...
