  • Patent number: 6868653
    Abstract: Device and method for the alignment of stacked products to be wrapped such as newspapers, magazines and books, with or without inserts, of any thickness or size. Sheet placers feed products into the device via a conveyor system equipped with pushers, set at predetermined positions. The products are aligned by engaging elements that rotate through a slot inside of which the conveyor pushers also slide. The engaging elements decrease in speed as they intercept the products, and align the products with the conveyor pushers as they are transported along the conveyor to a packaging area.
