Abstract

1281714 Drafting; lap stop motion MASCHINENFABRIK RIETER AG 17 July 1969 [26 July 1968] 36026/69 Heading DID In a double apron drafting arrangement comprising a cage 5 which guides the front ends of the aprons close to the nip of the delivery rollers 10, 11 and is pivoted about bottom apron roller 7, the cage is normally prevented from tilting by a pressure saddle 20 engaging the axle of the top apron roller 6 but when a lap 26 is built up on the lower delivery roller 11 the nose of apron 9 is lifted so causing the cage to rotate to the position shown in Fig. 2. The roving between rollers 6, 7 and rollers 10, 11 is broken by the rotation of the cage and because pressure is released from roller 6 the roving is no longer forwarded by the aprons and accumulates beneath the rollers until the arrangement is pieced up. Saddle 20 is mounted on a member 17 pivoted on the weighting arm 18 at 19 and member 17 also rotates when a lap is formed. A spring member 25 mounted on member 17 engages the axle 22 of roller 6 as it is pivoted away from its working position so that roller 6 is not pushed into contact with roller 3. In a further form cage 5 is constituted by separate upper and lower parts which are detachably connected.
