Method and appliance for feeding envelopes and fold strips in an adhesive binder involve gripper drum, grippers, block with spine.

摘要

The shared feeder appliance brings either the fold-strip or the envelope or both materials together in contact with the block's spine. The feeder consists of a gripper-drum (4). After the material has rolled along the block with synchronous speed, the grippers (3) perform an accompanying movement synchronous with the block-transport and at a tangent with the diameter of the gripper drum. The leading edge of the material remains at a certain angle in contact with the block-spine while the gripper drum continues rotating.
