Abstract
Abstract Apparatus for producing stationery assemblies comprising means for moving a plurality of superposed webs along a path of travel, tab-cutter which cuts a plurality of superposed tabs in said webs and bends the tabs so that their free ends extend outwardly of the webs and in a leading direction along said path of travel, and a roller adhesive applicator which rotates in a direction opposite to the direction of movement of the webs. A controlled amount of quickdrying adhesive is simultaneously applied to the free ends of the tabs by the roller, with the position of the roller relative to the webs and the speed of rotation thereof being adjustable to vary the amount of adhesive applied to the free ends of the tabs and also to vary the area of the tabs to which the adhesive is applied.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
Apparatus for producing stationery assemblies comprising means for moving a plurality of continuous superposed webs along a general path of travel, cutter means adjacent said path for forming a plurality of at least partially superposed tabs in said webs and for bending said tabs so that their free ends project outwardly from one side of said webs and said path of travel and extend in a leading direction along said path of travel, adhesive applying means comprising roller means mounted for rotation adjacent said path of travel on said one side thereof, said roller means being positioned to engage said free ends of said tabs and simultaneously apply a controlled amount of adhesive thereto as said webs are moved along said path, and means for rotating said roller means in a direction generally opposite the direction of movement of said webs so that said free ends of said tabs, upon engaging said roller means, are bent away from said webs.
Claim 2
Dependent Claim
160 words
Apparatus for producing stationery assemblies comprising means for moving a plurality of continuous superposed webs along a general path of travel, cutter means adjacent said path for forming a plurality of at least partially superposed tabs in said webs and for bending said tabs so that their free ends project outwardly from one side of said webs and said path of travel and extend in a leading direction along said path of travel, adhesive applying means comprising roller means mounted for rotation adjacent said path of travel on said one side thereof, said roller means being positioned to engage said free ends of said tabs and simultaneously apply a controlled amount of adhesive thereto as said webs are moved along said path, and means for rotating said roller means in a direction generally opposite the direction of movement of said webs so that said free ends of said tabs, upon engaging said roller means, are bent away from said webs.
Claim 3
Dependent Claim
65 words
Apparatus for producing stationery assemblies as defined in claim 1, comprising means for varying the disposition of said roller means toward and away from said webs and means for varying the speed of rotation of said roller means to variably control the amount of adhesive applied to said free ends of said tabs and the area of said tabs to which the adhesive is applied.
Claim 4
Dependent Claim
40 words
Apparatus for producing stationery assemblies as defined in claim 2, said web moving means comprising feed roller means receiving said webs after they have passed said adhesive applying means and urging said adhesively coated tabs into contact with one another.
