Abstract
A glue applicator for the installation of laminate flooring on subfloors has three laterally spaced nozzles for applying separate beads of glue onto the back of a plank of laminate flooring. Two nozzles are spaced for applying separate beads of glue along the lateral edges of a plank, the third nozzle is spaced for applying beads of glue through the center of the plank. Flanges on the sides of the glue applicator position the beads of glue on the back of a plank of laminate flooring and standoff flanges hold the nozzles above the back of the plank a sufficient distance for assuring that the glue applicator of this invention does not smear the beads.
Claims4
A glue applicator for the installation of laminate flooring on subfloor, comprising:
- three laterally spaced nozzles for applying separate beads of glue onto the back of a plank of laminate flooring, two nozzles are spaced for applying separate beads of glue along the lateral edges of a plank, the third nozzle is spaced for applying a bead of glue through the center of the plank, the nozzles for applying separate beads of glue along the lateral edges of the plank are sized and spaced for applying beads of glue that will bond the plank to the subfloor at its edges and such that glue will not flow beyond the edge of the plank, the nozzle for applying a bead of glue through the center of the plank is sized for applying a bead of glue that will bond the center of the plank to the subfloor;
- alignment flanges on the sides of the glue applicator for positioning the beads of glue on the back of a plank of laminate flooring;
- and
- standoff flanges for holding the nozzles above the back of the plank a sufficient distance to assure that the glue applicator does not smear beads of glue as they are being applied to the back of a plank, the standoff flanges are rounded to accommodate any change to the angle that the glue applicator is held with respect to the back of the plank without smearing the beads.
