A driven spider is mounted for rotation about an axis of rotation which is parallel to said pivotal axis. Squeeze rollers are rotatably mounted on said spider and revolvable thereby about said axis of rotation and adapted to act on and compress said squeeze tube. Spring means are provided which urge said frame towards said squeeze rollers.
