ABSTRACT:
In order to pivot lifting forks and press or contact roll arms, there is employed a single cylinder unit acting by means of a piston rod upon a crank arm of a shaft member. Rotation of this shaft member causes, by means of the press roll arms connected rigidly for rotation with such shaft member, pivoting of a press or contact roll. A lever which likewise is rigidly connected for rotation with the shaft member is hingedly connected with a pair of brackets at whose other end there is located a guide roller or roll which travels in a slotted guide of a guide lever carrying one of the lifting or lift forks for the lifting-in and lifting-out of the warp beam. The other lifting fork is carried by a second analogous guide lever. Both of the guide levers are operatively connected with a pivotal shaft. The arrangement is carried out such that during rotation of the shaft member operated by the cylinder unit through a first angular range or region only the contact or press roll performs a pivotal movement, whereas the guide roll moves without any effect within the slotted guide. Only during a further angular range of rotation of the shaft member, which follows the first angular range of shaft rotation, are the guide levers and therewith the lift forks rocked by the action of the guide roll which bears at the end of the slotted guide.
