An apparatus for joining sheet segments, typically rubberized, to one another to form an elongated strip, wherein a strip composed of sheet segments joined together is conveyed into a joining zone between rear and front conveyance zones in such a manner that the strip has a trailing end portion slightly projecting rearwardly from the rearmost ends of guide rails extending through the joining zone and front conveyance zone, whereupon a vertically movable pressing surface is brought into pressing contact with the trailing edge of the strip for causing the trailing edge to extend at a desired angle to a transverse direction of the joining zone. A sheet segment to be joined to such a strip is conveyed into the joining zone under the guidance of a vertically movable ride-on surface whereupon vertically movable edge portions are brought into pressing contact with the leading edge of the sheet segment for causing the leading edge to extend in parallel with the trailing edge of the strip. The pressing and ride-on surfaces and the edge portions are then withdrawn whereupon pressing rollers are brought into contact with a leading end portion of the sheet segment overlapped by a trailing end portion of the strip so that the overlapped portions of the strip and sheet segment are joined together. |
