Abstract: A spooling machine for the simultaneous spooling of at least two threads on an equal quantity of winding places, which are arranged so as to be adjacent to one another in a row, is equipped with a belt-type traversing device. The traversing is effected by means of carriers (28a-28d) which are moved in opposite directions and which fit on a revolving toothed belt (20) so as to be uniformly spaced (y), and alternately grasp the threads (8a-8d). The reversing points of the traversing areas of the individual winding places are marked by means of deflectors (47a-47d; 51a-51d). The effective spacing (z) between two corresponding deflectors (47a-51a; 47b-51b; 47c-51c; 47d-51d), which effective spacing (z) determines the traversing stroke is smaller than the center distance (x) between two traversing areas. This is exactly half as large as the spacing (y) between two adjacent carriers (28a-28d).

Abstract: A winding machine, comprises a machine frame, a winding mandrel which is connected with the machine frame during winding, traversing device including two belt runs movable near one another in opposite directions and provided with drivers, diverters each arranged at a respective one of reversing points of the traversing device and displaceable parallel to a winding axis, a sensing element abutting against a surface of a coil which is being wound, and a transmitting device which couples the diverters with the sensing element, the transmitting device including at least one displacing rod which connects the diverters with one another and extends parallel to the winding axis, a guiding rail with which the displacing rod is in engagement, the guiding rail and the traversing device being formed so that they are displaceable in correspondence with movement of the sensing element relative to one another at a right angle relative to the winding axis.

Abstract: An arrangement for melt spinning of synthetic high polymers comprising a spinning bar, rails arranged at a height of a nozzle set inserted in the spinning bar, and a device for exchanging the spinning bars and including a carriage with an arm hydraulically moveable from an inclined inwardly directed normal position to a horizontal working position, wherein a free end of the arm is connected with a table serving for receiving of the exchangeable nozzle set and provided with elements for centering and securing of the dismounted nozzle set.

Abstract: A machine for cutting a travelling tow of synthetic plastic filaments to produce staple fibers has a blade carrier from which cutting blades project and have their free ends secured to a concentric surrounding ring. The facing annular surfaces of ring and carrier are shaped to resemble portions of a hollow and of a solid sphere, respectively, and together define an annular cutting channel. A tow pressing ring is arranged skew to the axis of this channel, so that it enters into the channel at one side but is spaced from and defines with the inlet to the channel a gap at the opposite side. One or the other of the carrier and ring is positively rotated. When tow is fed through the gap into the channel it forms on the carrier one or more convolutions which are progressively pressed deeper into the channel by the pressing ring until they reach and are cut by the cutting blades.
