METHOD AND DEVICES TO ELIMINATE WRINKLES WHEN LOADING AND TO ELIMINATE DRAGGING WHEN UNLOADING A FLEXIBLE, NON-STRETCHING MATERIAL ON A FLEXIBLE AND STRETCHABLE CONVEYOR BELT

摘要

The invention considers the difference by which a flexible and non-stretching material (A), transported on a conveyor belt (B), next to a first cylinder (1), of loading, has a length of travel that is greater than the conveyor belt's (B), a surplus that when loading, wrinkles the material, and at the opposite end of the conveyor belt, on the unload cylinder (2), the material being dragged, it slips off the belt when unloading, wrinkling and dragging that are eliminated by inserting a cover device (3), that separates the material from the belt when loading it, as well as a blade (4), which, due to its attaching to the conveyor belt (B) and to its helical disposition, breaks the adhesion between the transported material and the belt when unloading, detaching the material (A) from the belt (B), and, due to a curtain type prolongation piece (5) that is attached to the blade (4), the transported material is prevented from being driven on the belt, which leads to eliminating the material wrinkling and dragging and ensuring a high precision transportation of the material.;Fig. (6) fully illustrates this invention.
