Abstract: A device (5) wherein, for splicing the facing edges (4a,4b) of a sheet (4) of unvulcanized rubber using a powered grip fixture (6) with a pressure member (11) and a counterpressure plate (36) for gripping the sheet (4) to a given pressure and imparting a given thrust on the edges (4a, 4b) of sheet (4) for bringing them together, the grip fixture (6) is moved back and forth along a route parallel to the edges (4a, 4b) of sheet (4) and defined by a guide (85) designed to move to and from an operating position wherein the counterpressure plate (36) and the edges (4a, 4b) of sheet (4) are substantially coplanar, and wherein lifting member (41, 64)(41, 65) cooperate with sheet (4) for lifting the respective edges (4a, 4b) onto the counterpressure plate (36) and into engagement with grip fixture (6 ).
