Abstract

Abstract This invention is concerned with a thin film of thermoplastic resin adhesive with a special arrangement of slits or cuts and a method of adhesive deposition or bonding in which the film of adhesive is applied to one surface, heat is applied to bring the adhesive to active condition and cause the film to assume a pattern directly related to the arrangements of slits or cuts and particularly effective for bonding.

An article as defined in claim 1 in which said slits are arranged in parallel rows with slits of one row opposite unslit portions of an adjacent row of slits.
Claim 2
Dependent Claim 40 words
An article as defined in claim 2 in which the ends of slits in one row overlap the ends of slits in an adjacent row by from about 15 percent to about 40 percent of the length of the slits.
Claim 3
Dependent Claim 40 words
An article as defined in claim 1 in which said film is a strip having a row of parallel slits extending in from an edge of said strip leaving a continuous portion of said strip extending lengthwise of said strip.
Claim 4
Dependent Claim 28 words
An article as defined in claim 4 in which said slits are disposed at an angle other than a right angle to the longitudinal direction of said strip.
Claim 5
Dependent Claim 32 words
An article as defined in claim 5 having rows of parallel slits extending in from opposite edges of said strip leaving a continuous portion of said strip extending centrally of said strip.
Claim 6
Dependent Claim 121 words
As an article for disposing normally solid heat-softenable polymer resin in a predetermined open pattern when placed on a surface and heated, a thin free film of said resin having a thickness not over about 0.03 inch and less than about one-third the width of the space between adjacent slits, said resin film when heat-softened being capable of drawing itself into a line pattern, said film being formed with slits spaced at distances of not over about three-sixteenths inch and being disposed and arranged to determine said pattern, said slits having lengths at least about equal to the greatest distance between any point on the edge of a slit and the closest point on a slit nearest to said first-mentioned point.
