Abstract
A compact handheld adhesive applicator is provided with a housing assembly and a cartridge assembly removably connected to the housing assembly. The cartridge assembly includes a primary spool for mounting an adhesive segment roll and a secondary spool for automatically winding a spent portion of the adhesive segment roll. A gear arrangement allows for numerous adhesive segments to be applied consecutively in a glide-type application or for a single adhesive segment to be accurately applied using a manual advance feature.
Claims19
An adhesive applicator, comprising:
- a housing;
- a primary spool mounted to the housing, the primary spool adapted to receive an adhesive roll including a wound supply of liner carrying an adhesive;
- a secondary spool mounted to the housing, the secondary spool adapted to collect portions of the liner advanced from the adhesive roll;
- and
- a circular rotatable advancement member for advancing indefinite amounts of liner from the adhesive roll, the rotatable advancement member mounted on the housing in a position that is non-axial with the primary and secondary spools and the rotatable advancement member partially extending from an opening in the housing such that the rotatable advance member is adapted to be contacted and rotated by a user to advance a desired amount of the liner from the adhesive roll;
- the rotatable advancement member being movable from a disengaged position wherein the advancement member is disengaged from one of the primary spool and the secondary spool to an engaged position wherein the rotatable advancement member is engaged with one of the primary spool and the secondary spool, and wherein the advancement member is biased toward the disengaged position.

An adhesive applicator, comprising:
- a housing;
- a cartridge removably connected to the housing, the cartridge having a primary spool including an adhesive roll having a wound supply of a liner carrying an adhesive and a secondary spool adapted for collecting portions of the liner advanced from the adhesive roll;
- and
- a circular rotatable track wheel adapted for advancing variable amounts of liner from the adhesive roll, the rotatable track wheel being in a position that is non-axial with the primary and secondary spools, wherein rotation of the track wheel causes a desired amount of the liner to advance from the adhesive roll;
- the track wheel being movable from a disengaged position wherein the track wheel is disengaged from one of the primary spool and the secondary spool to an engaged position wherein the track wheel is engaged with one of the primary spool and the secondary spool, and wherein the track wheel is biased toward the disengaged position.

An adhesive applicator, comprising:
- a rotatable adhesive roll including a wound supply of a liner carrying an adhesive thereon;
- a take-up roll having a portion of the liner connected thereto, the take-up roll adapted for collecting portions of the liner advanced from the adhesive roll;
- and
- a rotatable advancement member for advancing an indefinite amount of liner from the adhesive roll, the rotatable advancement member being non-axial with the adhesive roll and the take-up roll, and the rotatable advance member being rotatable 360 degrees about an axis of the rotatable advancement member, wherein the rotatable advancement member is adapted to be rotated to advance a desired amount of the liner from the adhesive roll;
- the rotatable advancement member being movable from a disengaged position wherein the advancement member is disengaged from one of the adhesive roll and the take-up roll to an engaged position wherein the rotatable advancement member is engaged with one of the adhesive roll and the take-up roll, and wherein the advancement member is biased toward the disengaged position.
