发明名称 Method for producing a continuous band of rubberized fabric having transversal reinforcing metal elements
摘要 A method is disclosed for accurately and readily forming a continuous band of rubberized fabric having transversal reinforcing metal elements by butt-splicing wherein a first and second piece of rubberized fabric having transversal reinforcing metal elements are positioned such that the initial end of the second piece is a predetermined distance from the terminal end of the first piece on a common plane with the reinforcing metal cords running parallel to the ends of the pieces, butt-splicing the pieces, without overlapping, by mutually approaching the pieces, obtaining a uniform accumulation of the rubber of the rubberized fabric about the reinforcing cords as well as a local thickening of the latter at a zone symmetrically situated with respect to the contact surface of the ends and whose width is proportional to the pre-established distance wherein the pieces are bound by the operating parts of the splicing apparatus, releasing the pieces from the operating parts of the splicing apparatus and winding up the continuous band on a collecting drum. An apparatus for producing the continuous band is also disclosed where the operating parts have a base element and a movable ledger capable of locking the pieces of rubberized fabric on a common plane by a series of fingers.
