Abstract
Abstract An automatic adhesive applicator for applying successive transverse adhesive strips on a continuously moving web. An adhesive dispenser is mounted for reciprocating movement along a predetermined path extending transversely of the continuously moving web. The dispenser includes a rotatable cam follower adapted to engage cam surfaces located in the outer surface of a rotatable cylinder which operates to drive the dispenser back and forth along the predetermined path. The cam surfaces operably drive the dispenser at a constant speed along that portion of the path during which adhesive is dispensed, and return the dispenser at a constant speed along the same portion of the path. At each end of the path, the cam surfaces reverse the direction of the cam follower and therefore the dispenser with harmonic motion to permit reliable high speed operation with minimum stress and wear on the equipment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
An improved automatic adhesive applicator for applying successive transverse adhesive strips on a continuously moving web, said applicator comprising: guide means extending transversely of at least a part of said web at an angle relative to the direction of the web; an adhesive dispensing means mounted on said guide means for reciprocal movement along a path of predetermined length, said adhesive dispensing means being closely spaced from said web and adapted to apply a strip of adhesive to said web while transversing a preselected portion of said path; drive means including a rotatable cylinder means positioned generally parallel to said guide means and operable to drive said dispensing means back and forth along said predetermined path when said cylinder means is rotated, the combination of movement of said dispensing means and the continuous movement of the web relative to said dispensing means being operable to apply adhesive to said web along a transverse path differnet from the path traversed by said dispensing means.
Claim 2
Dependent Claim
163 words
An improved automatic adhesive applicator for applying successive transverse adhesive strips on a continuously moving web, said applicator comprising: guide means extending transversely of at least a part of said web at an angle relative to the direction of the web; an adhesive dispensing means mounted on said guide means for reciprocal movement along a path of predetermined length, said adhesive dispensing means being closely spaced from said web and adapted to apply a strip of adhesive to said web while transversing a preselected portion of said path; drive means including a rotatable cylinder means positioned generally parallel to said guide means and operable to drive said dispensing means back and forth along said predetermined path when said cylinder means is rotated, the combination of movement of said dispensing means and the continuous movement of the web relative to said dispensing means being operable to apply adhesive to said web along a transverse path differnet from the path traversed by said dispensing means.
Claim 3
Dependent Claim
26 words
An improved automatic adhesive applicator as set forth in claim 1 wherein said drive means is continuously synchronized with the movement of said continuously moving web.
Claim 4
Dependent Claim
44 words
An improved automatic adhesive applicator as set forth in claim 1 wherein said dispensing means is in close proximity to the surface of said web such that precisely applied strips of adhesive having a uniform width and distinct ends are applied to said web.
Claim 5
Dependent Claim
33 words
An improved adhesive applicator as set forth in claim 1 wherein said rotatable cylinder includes a pair of cam surfaces extending substantially continuously around said cylinder means and between opposite end portions thereof.
Claim 6
Dependent Claim
48 words
An improved automatic adhesive applicator as set forth in claim 4 wherein said adhesive dispenser includes a cam follower assembly disposed between said cam surfaces of said cylinder means whereby rotation of said cylinder means causes said dispensing means to be driven back and forth along said path.
Claim 7
Dependent Claim
79 words
An improved automatic adhesive applicator as set forth in claim 5 wherein said cam follower Assembly is positioned above said guide means and includes a pair of rotatable bearings positioned on opposite sides of a third bearing, said bearings being disposed between said cam surfaces mounted upon a rotatable cam follower block such that rotation of said cylinder means causes said bearings and cam follower block to rotate while said dispensing means transverses back and forth along said path.
Claim 8
Dependent Claim
51 words
An improved adhesive applicator as set forth in claim 6 wherein said third roller is directed toward the axis of said cylinder menas, and each of said pair of rollers are generally directed toward said axis, each of said pair of rollers being tapered in a direction toward said cylinder means.
Claim 9
Dependent Claim
42 words
An improved adhesive applicator as set forth in claim 4 wherein said cylinder means includes bearing blocks having bearings therein at each end thereof, said blocks being removably mounted to said applicator, such that removal of said cylinder means is easily facilitated.
Claim 10
Dependent Claim
47 words
An improved automatic adhesive applicator as set forth in claim 1 where said drive means includes a rotatable drive train for rotating said cylinder means, and said drive train includes a phase shifting means for shifting the location of said strip of adhesive in the web direction.
