Transfer adhesive dispensing device

A transfer adhesive dispensing device suitable for dispensing adhesive onto a substrate from a convolutely wound roll of transfer adhesive consisting of a web of adhesive, a release liner and a core having axially extending blind cavities terminating at edge walls, said device comprising:

• a housing;
• an applicating roller mounted on the forward portion of said housing, a portion of said roller's periphery projecting beyond said housing;
• a tape support rotatively mounted in said housing, said support having axially extending projection means engaging said core for interlocking engagement and for engaging edge walls of a said core thereby positioning said core with the axis thereof in a predetermined parallel spaced relationship to the axis of said roller and in a predetermined axial relationship to said tape support holding said adhesive and said liner on said core in alignment with respect to a predetermined axial portion of the surface of said applicating roller;
• a takeup roller mounted in said housing for receiving and holding spent liner after said adhesive web has been applied to said substrate, said takeup roller being mounted in spaced parallel relationship to said applicating roller;
• said roll of transfer adhesive being positioned from a said core about said applicating roller, with the liner engaging the applicating roller, then with the liner extending around the wound roll engaging the web of adhesive therein and then contacting said takeup roller;
• drive means associated with said tape support and said takeup roller for transmitting rotational motion from said tape support to said takeup roller upon rotation of said tape support by rotation of said core during unwinding of said web of adhesive and application of said adhesive strip to said substrate, said takeup roller being simultaneously rotated in the opposite direction to increase the contact of the liner with the wound roll;
• and
• brake means for stopping the rotation of the tape support and thereby said core, whereby when said device is pulled after said brake is applied, the adhesive applied to the substrate will be severed from the adhesive remaining in the device.
