  • Patent number: 5199550
    Abstract: A belt-type transfer apparatus suitable for transferring objects such as medial ampules or vials or bottles or cans stuffed with beverages or foods, by clamping the objects between successive pairs of opposing belts which are wound on two rows of multiplicity of successive rollers arranged in the direction of the transfer. The arrangement is such that, in the region near one of the rollers of one of said rows around which belts are wound to provide different directions of transfer, the belts associated with the rollers of the other row are arranged to intersect each other at their sides for clamping said object, so that these belts are made to flex when the object passes through the above-mentioned region, thus allowing a smooth change of direction of the transfer. At least one of the rollers disposed in the region where the transfer direction is changed is a sectional roller which is composed of a plurality of pulley segments carried by a common shaft for independent rotation.
