1. A system for use in the manufacturing of paperboard corners, the system comprising:
a paper sheet processing assembly for manufacturing the paperboard corners from an engaged paper sheet engaged therein; and
a splicing apparatus for splicing together the engaged paper sheet with a replenishing paper sheet, the engaged paper sheet being engaged into the paper sheet processing assembly downstream from the splicing apparatus for processing the engaged paper sheet into the paperboard corners, the splicing apparatus comprising:
an engaged sheet holder for holding the engaged paper sheet;
an engaged sheet cutter for cutting the engaged paper sheet to form a free engaged paper end having a substantially straight engaged paper edge extending substantially perpendicular to a longitudinal axis of the engaged paper sheet;
a replenishing sheet holder separate from the engaged sheet holder for holding the replenishing paper sheet;
a replenishing sheet cutter for cutting the replenishing paper sheet to form a free replenishing paper end having a substantially straight replenishing paper edge extending substantially perpendicular to a longitudinal axis of the replenishing paper sheet;
a sheet end alignment device for positioning the free engaged paper end and the free replenishing paper end relative to each other such that the free engaged paper end and the free replenishing paper end are substantially aligned with each other and such that the engaged paper edge extends substantially parallel to the replenishing paper edge; and
an adhesive tape applicator distinct from the engaged and replenishing sheet holders for applying an adhesive tape simultaneously to the aligned free engaged and replenishing paper ends such that the adhesive tape extends partially over the engaged paper sheet and partially over the replenishing paper sheet to join the free replenishing paper end to the free engaged paper end;
wherein the adhesive tape applicator comprises an abutment member positionable on one side of a front end of the free replenishing paper end and the free engaged paper end aligned with each other and a tape receiver for receiving the adhesive tape with an adhesive side thereof towards the free replenishing paper end and the free engaged paper end, the tape receiver and the abutment member being movable towards each other such that the free engaged and replenishing sheet ends are sandwiched between the abutment member and the tape receiver to thereby apply the tape over the free engaged and replenishing sheet ends.
