Abstract

1428496 Yarn feeding; belt and roller arrangement CHAVANOZ SA 22 June 1973 [26 June 1972] 29795/73 Heading DID A yarn feeding device for textile machines, particularly false twist texturising machines, comprises a rotating drum 1 and an endless belt 3 which in the operational position is applied against the drum over a first arc (Figure 3), the yarn 10 passing between the belt and the drum, and the belt 3 being mounted on two idling rollers 4, 5 carried by a support arm 8 for movement between the operational position and a non-operational position in which the belt 3 is out of contact with the drum 1, the support arm 8 having means pretensioning and maintaining the belt in an intermediate position between the operational and non-operational positions (Figure 2), the belt in this intermediate position being in contactwiththedrum over a second smaller arc and at a pressure lower than those utilised in the operational position. The positioning means comprise an adjustable abutment 13 mounted on an arm 14 pivoted about axis 17 fixed relative to the pivot 9 of the support arm 8. In the intermediate position i.e. at the start-up of the machine, the abutment 13 presses the belt 3 against an arc of the drum 1. Also in the intermediate position, the pretensioning means e.g. roller 15 mounted on arm 16 pivoted at 17. acts on the belt 3 to provide the required tension in the belt. The force exerted by the belt on the drum is adjusted so that the forwarding force exerted on the yarn 10 is less than the breaking tension of the yarn. The positioning means 13 and pretensioning means 15 are acted upon by springs 18, 20 so that when the support arm 8 moves to the operative position (Figure 3) the positioning means and pretensioning means are moved to an inoperative position. In a further embodiment, the pretensioning means acts to vary the distance between the axes of the idling rollers in response to movement of the positioning means between operative and inoperative positions.
