Abstract: A tape applying apparatus adjustable to accommodate various width taping heads. The apparatus includes a base, left and right bed portions separated by a central open portion, and left and right filler plates mounted in the central open portion. The distance between the filler plates can be adjusted to adjust the width of the central open portion and accommodate lower taping heads of different widths. Replaceable front and rear guards are placed on the front and rear of the bed across the ends of both filler plates. The apparatus can also include an upper frame for supporting an upper taping head. The upper frame includes two support members. A rear spacer connecting the two support members, a front support plate, and a top cover can be replaced or adjusted to accommodate an adjustable upper taping head width.
