Embodiment Construction

[0022] The transmission design of the two drafting systems 1a, 1b of the double-head draw frame shows two electric motors 2 and 3 and the lower rolls of the drafting system I a, II a, III a and I b, II b, III b respectively the connection between. The lower rolls I a, II a, III a and I b, II b, III b of the drafting system are specifically driven by toothed belts. The rotation of the upper roll of the drafting system (see Figure 7) is affected by the contact pressure of the upper roll on the lower roll.

[0023] A driving pulley 4 is non-rotatably mounted on a shaft extension 2 a of a motor 2 (main motor), and is connected with a driven pulley 6 non-rotatably provided on a main shaft 7 through a continuously rotating toothed belt 5 . The main shaft 7 coaxially drives the two lower rollers Ia and Ib. An electromagnetic coupling 8 is provided between the pulley 6 and the lower roller 1a, and an electromagnetic coupling 9 is provided between the pulley and the lower roller 1b. ...

Abstract

In the case of an apparatus on a spinning preparation machine, e.g. a draw frame, flat card, combing machine or the like, in particular a double-head draw frame, with at least two driven drafting systems having force-transmitting means for driving drafting rollers of the drafting systems and at least one drive motor, a coupling is present between a drive motor and a drive shaft. To allow the effectiveness and efficiency to be substantially increased in a structurally simple and cost-effective manner, the respective drive chains are connected via a respective controllable coupling to the motor and the rotational speed of the motor can be reduced for the engagement and disengagement process.

Description

technical field [0001] The invention contemplates a device on a spinning preparation machine, such as a draw frame, flat card, comber, etc., in particular a double-head draw frame, which has a At least two driven drafting systems for drafting at least one fiber sliver with drafting rollers forming a drafting roller pair, the device has a force transmission device for driving the drafting rollers and at least one drive motor, the electric coupling is arranged at Between drive motor and drive shaft. Background technique [0002] In the textile industry draw frames are often used to flatten carded sliver. A very simple and cost-effective variant is a machine with two drafting systems working in parallel, called a double-head draw frame. In these machines, in particular with two feed creels and two can coilers or can changers, the working elements on both sides are driven by corresponding common drives. However, the consequence is that if one of the two sides fails, both side...
