Abstract
Abstract Tile products from a vertically aligned stack are moved by a continuously moving product conveyor into an adhesive coating and paper covering apparatus. There, adhesive is first applied in a controlled pattern to a portion of paper from a continuous roll and the adhesive-coated paper is then cut to size and applied to the tile. The final product comprises a tile upon which has been deposited and bonded an adhesive coating in a predetermined controlled pattern and covered with a protective sheet of paper which then can be peeled away when the tile is installed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A METHOD OF PRODUCING A PRESSURE-SENSTIVE ADHESIVE TILE PRODUCT COMPRISING THE STEPS OF: CONVEYING A SUCCESSION OF TILES AT A UNIFORM VELOCITY ALONG A STRAIGHT-LINE PATH, MOVING A CONTINUOUS WEB OF PROTECTIVE PAPER AT SAID UNIFORM VELOCITY PAST AN ADHESIVE COATING IN A PREDETERCOATING SAID PAPER WITH AN ADHESIVE COATING IN A PREDETERMINED PATTERN, CUTTING SAID ADHESIVE-COATED PROTECTIVE PAPER TO SEPARATE PREDETERMINED LENGTHS WHILE SAID WEB OF PAPER IS MOVING AT SAID UNIFORM VELOCITY, MOVING SAID SEPARATE PREDETERMINED LENGTHS OF PAPER TO A POINT IN LINE WITH AND AT THE SAME UNIFORM VELOCITY AS SAID TILES, WITH THE ADHESIVE-COATING SIDE OF THE PROTECTIVE PAPER FACING THE TILES, AND APPLYING ROLLING CONTACT PRESSURE AGAINST THE ADHESIVECOATED PAPER TO PRESS IT AGAINST THE TILES WHILE SAID TILES AND SAID PREDETERMINED LENGTHS OF PAPER ARE CONTINUOUSLY MOVING ALONG AT SAID UNIFORM VELOCITY.
Claim 2
Independent Claim
139 words
A METHOD OF PRODUCING A PRESSURE-SENSTIVE ADHESIVE TILE PRODUCT COMPRISING THE STEPS OF: CONVEYING A SUCCESSION OF TILES AT A UNIFORM VELOCITY ALONG A STRAIGHT-LINE PATH, MOVING A CONTINUOUS WEB OF PROTECTIVE PAPER AT SAID UNIFORM VELOCITY PAST AN ADHESIVE COATING IN A PREDETERCOATING SAID PAPER WITH AN ADHESIVE COATING IN A PREDETERMINED PATTERN, CUTTING SAID ADHESIVE-COATED PROTECTIVE PAPER TO SEPARATE PREDETERMINED LENGTHS WHILE SAID WEB OF PAPER IS MOVING AT SAID UNIFORM VELOCITY, MOVING SAID SEPARATE PREDETERMINED LENGTHS OF PAPER TO A POINT IN LINE WITH AND AT THE SAME UNIFORM VELOCITY AS SAID TILES, WITH THE ADHESIVE-COATING SIDE OF THE PROTECTIVE PAPER FACING THE TILES, AND APPLYING ROLLING CONTACT PRESSURE AGAINST THE ADHESIVECOATED PAPER TO PRESS IT AGAINST THE TILES WHILE SAID TILES AND SAID PREDETERMINED LENGTHS OF PAPER ARE CONTINUOUSLY MOVING ALONG AT SAID UNIFORM VELOCITY.
Claim 3
Dependent Claim
49 words
The method as defined in claim 1 wherein said protective paper is cut such that its length is greater than the length of one of said tiles and wherein said protective paper is applied to said tiles such that the paper overlaps at least one edge of the tiles.
Claim 4
Dependent Claim
80 words
The method as defined in claim 1 wherein said adhesive is applied in a predetermined area on said protective paper such that when said adhesive-coated paper is applied to each said tile the adhesive coated area is set back from each edge of said tile thereby defining an adhesive pattern bonded to the tile wherein adhesive is bonded only to the central portion of the tile leaving a border around the periphery of the tile where no adhesive is bonded.
Claim 5
Independent Claim
90 words
A method of producing a pressure-sensitive adhesive tile product comprising: moving a continuous web of paper past an adhesive applicator at a uniform velocity, applying adhesive to selected portions of said paper as said paper is continuously moving at said uniform velocity, severing said continuous web of paper into separate predetermined lengths while said web is moving at said uniform velocity and, transferring said separate predetermined lengths of adhesive-coated paper to a succession of continuously moving tile products which are moving at substantially the same uniform velocity as said paper.
Claim 6
Independent Claim
90 words
A method of producing a pressure-sensitive adhesive tile product comprising: moving a continuous web of paper past an adhesive applicator at a uniform velocity, applying adhesive to selected portions of said paper as said paper is continuously moving at said uniform velocity, severing said continuous web of paper into separate predetermined lengths while said web is moving at said uniform velocity and, transferring said separate predetermined lengths of adhesive-coated paper to a succession of continuously moving tile products which are moving at substantially the same uniform velocity as said paper.
Claim 7
Dependent Claim
42 words
The method as described in claim 4 wherein said predetermined length for severing said paper corresponds to a length slightly greater than the length of a tile product thereby to provide a paper overlap on at least one edge of said tiles.
Claim 8
Dependent Claim
50 words
The method as defined in claim 4 wherein said adhesive is applied to said paper in an area which is less than the surface area of said tile product thereby to define an adhesive surface on said tile product which is set back from the peripheral edges of said tiles.
Claim 9
Dependent Claim
36 words
The method as defined in claim 4 wherein said adhesive is a hot melt adhesive and is transferred from a heated adhesive storage pot where the adhesive is maintained in a liquefied state to the paper.
