SPLICING APPARATUS FOR ROSS-FLUTE CORRUGATED BOARD ABSTRACT OF THE DISCLOSURE Apparatus is disclosed for splicing together successive sections of single facer corrugated board having planar and corrugated fibrous layers, which sections are initially conveyed colinearly in spaced relation at uniform speed with the flutes extending in the direction of travel of the sections, charac- terized by the provision of a reciprocatory vacuum bar feed member operable initially to accelerate a subsequent section relative to a preceding section to a position in which a protruding layer portion at the trailing end of the preceding section is in superposed relation relative to a protruding layer portion at the leading end of the subsequent section, and subsequently to displace the section at the lower uniform speed at the moment at which the adjacent ends of the sections are in overlapping relation, whereupon the superposed portions may be bonded together to connect the sections to form a continuous web having longitudinally extending flutes. The vacuum bar feed member has a profiled upper surface containing grooves for receiving the corruga- tions of the subsequent section, which grooves are evacuated to maintain the section, by suction, in engagement with the vacuum bar feed member.
