Abstract
A conveyor is disclosed for labelling apparatus. The conveyor comprises a plurality of clamps and endless carrier for the clamps. Each clamp is urged to a closed position by a spring and is adapted to be held in an open position for receiving an unlabelled folder. Means closes each clamp to grip sheet material and hold it while it is being labelled for purposes of accurate receipt of applied labels. The body portion presents a base which supports clamped material. A moveable clamp jaw is secured to a member which is adapted to slide in and out of the body portion. The spring means is associated with the member to urge the clamp jaw towards the clamp base. The member has mounted thereon, remote from the jaw, a roller means adapted to rotate about an axis perpendicular to the longitudinal axis of the member. A slider cam is laterally moveable in the body portion and is in contact with the roller. The slider cam has upper and lower cam segments to provide respectively open and closed positions for the clamp. The cam upper segment has a depressed area to catch the roller means and hold said clamp open against closure pressure exerted by the spring. Means is provided for opening and closing the clamps as the conveyor moves.
