APPARATUS AND METHOD FOR MAKING AN INDEFINITE LENGTH COMPOSITE SHEET OF VERY LARGE PREDETERMINDED WIDTH FROM INDEFINITE LENGTH SHEET STOCK OF RELATIVELY SMALL WIDTH

摘要

Device and method for forming a composite sheet of indefinite length and relatively small width. The device comprises a feed roller (10) consists of a material in synthetic rubber sheet relatively narrow and of indefinite length, and a conveying device (12) that scrolls in a horizontal direction to a cutting device (14 ) a sheet of the narrow roll having a length equal to the relatively large width of the Desired composite sheet roll. After the advancement and cutting the desired length of the narrow roll, the cut sheet (11) is laterally transferred by a transport head (20) has suction alternative way movement cover with its edge the anterior edge of the posterior previously cut sheet and laterally offset, which has the effect of increasing the dimension of the composite sheet (29). A conveying device (12) feeds the composite sheet in the transverse direction to dispose successively lap joints (26) of the sheet in a pressing station (30) for covering joints or lap joints (26) are successively presses to increase their resistance. The composite sheet then defile through a takeoff powder applicator (36) which applies decollage powder on both sides of the sheet to prevent sticking together of composite sheets (29), which are not polymerized during storage in roll form. Downstream of the applicator (36) of take-off powder composite sheet (29) runs through a variable voltage regulator (38), a sheet cutting device (39) which cuts the sheet has the Desired width, up to a winding station (40) composite sheet, or it is wound on a mandrel for storage and subsequent polymerization. Between the feed roller (10) roll of narrow and long sheet and the cutting device (14) is a station
