An apparatus for applying a length of adhesive tape from a supply of adhesive tape along the length of a leading edge of a roll of web material includes a cutting mechanism for cutting the length of web material to form a length of leading edge on the roll of web material. An application mechanism of the apparatus is configured to remove adhesive tape from the supply of adhesive tape and apply adhesive tape along a length of the leading edge of the web material. A take-up mechanism removes a liner from the adhesive tape during the application of the adhesive tape to the leading edge. A buffing mechanism contacts the adhesive tape applied along the length of the leading edge to insure contact between the adhesive tape and an outer layer portion of the roll of web material that is directly adjacent the leading edge. A cutoff mechanism cuts the adhesive tape to form the length of adhesive tape along the leading edge of the web material.

Apparatus for applying adhesive tape

A definite length dispensing apparatus for dispensing thin adhesive tape includes a rotatable feed mechanism, a drive assembly and a rotatable stripper mechanism. The feed mechanism includes a plurality of spaced feed discs that are configured to remove a continuous strip of adhesive tape from the supply of adhesive tape. The drive assembly includes a manually operated lever arm which is coupled to the feed mechanism through a gear assembly. The drive assembly drives the feed mechanism. The stripper mechanism is positioned adjacent to the feed mechanism. The stripper mechanism includes a plurality of spaced stripper discs, with each stripper disc having a peripheral edge defined by alternating curved and straight edge sections. Adjoining stripper discs are rotated relative to one another such that a curved section of one stripper disc is adjacent to the straight section of an adjacent stripper disc. There are multiple feed discs for every one stripper disc.

Adhesive tape dispenser

A device adapted to apply a length of adhesive from a supply length of the adhesive releasably adhered to a liner along the length of an elongate member. A head carrying a plurality of pressure rollers is positioned in a contact position so that a first one of the pressure rollers presses the adhesive against the side surface of the elongate member at about a predetermined position adjacent the first end of the elongate member, and then the head is positioned in a pressure position so that upon further movement of the elongate member along the path all of the pressure rollers will cause the adhesive to be firmly pressed into engagement along the elongate member through the liner. The adhesive is cut adjacent a last pressure roller on the head after a length is applied, and the newly severed end of the adhesive is then moved from adjacent the last pressure roller to adjacent the first pressure roller in preparation for application of adhesive to the next elongate member.
