Embodiment Construction

[0037] In FIG. 4A there is a first embodiment of the winding device according to the invention, which is an improvement of the known winding device according to FIG. 1 . During production, the yarn 1 or ribbon reaches the first turning guide roller 2 of the winding device. From there, the yarn 1 advances towards a yarn tension sensor 13 fitted with deflecting guide rollers. Embodiments of the yarn sensor 13 will be described in detail below. The yarn 1 advances from the yarn tension sensor 13 to a yarn support device 14 which may be a deflecting guide roller rotatably mounted on a support 15a of the control device 15 . The control device 15 additionally comprises a yarn deflecting device 6, for example, in this embodiment, a straight diverting bow, and also a pressure roller 7, which first presses the yarn 1 against the The surface of the core 8 is then pressed against the periphery of the forming bobbin 9 as the bobbin 9 is formed from the supplied yarn. The cartridge core...

Abstract

A bobbin winding device for generating a bobbin by winding a thread or bandlet onto a bobbin core comprises fixing means ( 12 ) for holding a bobbin core ( 8 ) and rotating it around an axis of rotation (A), thread-pressing means ( 7 ) for pressing a thread ( 1 ) or bandlet against the peripheral surface of a bobbin ( 9 ) that builds up on the bobbin core ( 8 ), whereby the thread-pressing means are movable essentially radially relative to the axis of rotation (A), a traversing thread guide ( 10 ) located close to the thread-pressing means ( 7 ) for reciprocating the thread ( 1 ) or bandlet along the axis of rotation (A), and thread-support means ( 14 ) for conducting the thread supplied to the bobbin or bobbin core, respectively, in an axially stationary manner relative to the axis of rotation (A). The thread-pressing means ( 7 ) are movable essentially radially relative to the axis of rotation (A) together with the thread-support means ( 14 ) so that the distance (z) between the thread-pressing means ( 7 ) and the thread-support means ( 14 ) will remain constant.

Description

technical field [0001] The invention relates to a winding device for winding yarn or ribbon onto bobbin cores according to the preamble of claim 1 . Background technique [0002] The winding device winds the yarn or ribbon onto a bobbin core, usually having a cylindrical or conical shape, to form a bobbin. In the schematic side view of the known winding device shown in Fig. 1, during production, the yarn 1 reaches the first turning guide roller 2 of the winding device. From there, the yarn proceeds to a "tensioner roller 3", which is a spring-loaded deflectable diverting guide roller, on which the yarn is diverted and tensioned. The yarn advances from a tensioning roller 3 to another deflection guide roller 4 and from 4 to a control device 5 . The control device includes a yarn deflection device 6 that can be made into a turning arc structure and a pressing roller 7, which first presses the yarn on the circumferential surface of the bobbin core 8 at the beginning of the wi...
