The apparatus comprises a splicer foot including a splicer foot frame, a first continuous unitary V-shaped axle, and two non-powered lower rollers. The splicer foot frame has an opening defined therein having opposing sides. The first continuous unitary V-shape axle has two arms attached to the opposing sides of the opening. The two non-powered lower rollers are mounted on the two arms of the first continuous unitary V-shaped axle so that the two non-powered lower rollers are arranged in a V-shape pattern. The apparatus further comprises a plurality of powered upper rollers configured to operate in coordination with the lower rollers to engage the two ends of the sheet of tire material.
