  • Patent number: 4050573
    Abstract: Two receiving conveyors of the station extend at opposite sides of the longitudinal axis of an intake conveyor and have their own longitudinal axes inclined to that of the intake conveyor so as to intersect the same at a point longitudinally spaced from all of these conveyors. A curved intermediate conveyor extends from the discharge end of the intake conveyor to the receiving end of the receiving conveyor and is pivotable about a vertical pivot axis passing through this point. A drive advances the intake and receiving conveyors and drives coupling members which are provided on the receiving conveyor and which can engage with cooperating coupling members on the intermediate conveyor.

  • Patent number: 3993188
    Abstract: A transporting arrangement for delivering products which are deposited at a first cycle at one end of an endless conveyor at a second higher cycle from the other end thereof. The arrangement includes an endless conveyor having an upper run moving at a first speed onto which the products to be transported are placed uniformly spaced from each other and a first chain having a run parallel to the upper run and movable in the same direction and at the same speed as the upper run. A second chain, driven at a higher speed than the first speed, carries on a run parallel to the upper run a plurality of entrainment members, each movable from a rest to an operating position, and moved to the latter position when the respective entrainment member overtakes one of a plurality of actuating means fixed equally spaced from each other to the first chain.

  • Patent number: 3982642
    Abstract: Method of storing and transporting individual paper sheets abutting against each other to form a staple of sheets, in which a precompressed staple of sheets resting between upright support members on a support surface of a first magazine is gripped at opposite ends by clamping jaws of a gripper, which compresses the staple further to a self-supporting body, whereafter the body is lifted from between the support members of the first magazine and transported between support members of a second magazine, spaced from the first, at which the body is then relaxed by removing the clamping jaws; and an arrangement for carrying out the method.
