  • Patent number: 4856692
    Abstract: A feeding apparatus for feeding a material from a material supply to a further apparatus, particularly a packaging apparatus. The apparatus comprises a storage buffer for storing an amount of the material, a first feed arrangement for feeding the material from the material supply to the storage buffer, and a second feed arrangement for feeding the material from the storage buffer to the further apparatus. The storage buffer comprises a plurality of movable rollers and a plurality of fixed rollers disposed above the movable rollers. The material is wound alternately between the fixed and movable rollers. The movable rollers are movable toward the fixed rollers by the tension in the material, and are movable away from the fixed rollers under the influence of gravity. This enables the material to be fed continuously to the further apparatus during an interruption of the material supply.
