Abstract
An apparatus and method are provided for applying adhesive to an outer circumference of a section of tubing. The apparatus includes opposed grippers with concave adhesive transfer areas that can be moved into surrounding relationship with the tubing. Adhesive dispensing passages communicate with the adhesive transfer areas for delivering adhesive to the tubing. Counterbores are at opposed ends of the adhesive transfer areas and communicate with a vacuum source for removing excess adhesive.
Claims9
An apparatus for applying adhesive to an outer circumferential surface of a section of tubing comprising:
- a) first and second grippers having tube-mating faces, said faces each being formed with a concave adhesive transfer area dimensioned and disposed for surrounding said outer circumferential surface of said tubing;
- b) first and second adhesive supply passages extending through said first and second grippers and into communication with said adhesive transfer areas for delivering said adhesive to said adhesive transfer areas;
- c) counterbores at opposite respective ends of said adhesive transfer areas, and;
- d) a vacuum apparatus communicating with said counterbores for removing excess adhesive.
An apparatus for applying adhesive to an outer circumferential surface of a section of substantially cylindrical tubing, said apparatus comprising first and second grippers, each said gripper having an upper end mountable to means for moving said grippers toward and away from one another and an opposite lower end, each said gripper further having a tube mounting face in proximity to said lower end, each said tube mounting face being formed with a substantially horizontal concave semi-cylindrical adhesive transfer area extending therethrough, front and rear counterbores being formed in each said tube mounting face at opposite respective ends of each said adhesive transfer area, said adhesive transfer area, said front counterbore and said rear counterbore in said first gripper being disposed to register respectively with said adhesive transfer area, said front counterbore and said rear counterbore of said second gripper, first and second adhesive passages formed respectively in said first and second grippers for delivering adhesive to upper portions of said adhesive transfer areas, a vacuum channel formed in at least one of said tube mounting faces and communicating with said front and rear counterbores, and a vacuum source communicating with said vacuum channel for removing excess adhesive from said counterbores.
