Abstract Apparatus for applying a heat sensitive adhesive strip to a stack of paper sheets comprises rotatable bipartite clamping means and means for biasing the clamping means into abutment with the stack of paper sheets, whereby the stack of sheets are compressed and held. Below an edge of the held stack of sheets there is provided a pair of spaced strip guides which support the strip with its adhesive side facing the edge, and below the strip guides there is provided three heated platens. A motor driven cam drives a T-bar slidably coupled to the clamping means and during operation of the motor the T-bar rotates the clamping means, thereby moving the stack of sheets downwardly. While moving downwardly the edge of the stack of sheets abuts the adhesive side of the strip and moves the other side of the strip against the platens. Means are provided for biasing the platens against said other side of the strip, thereby fixing the adhesive strip to the stack of paper sheets to form a book.

Claim 3
Dependent Claim
33 words
Apparatus as defined in claim 1 wherein said means for rotating the clamping means includes biased means slidably coupled to a frame, and means responsive to a motor for moving the biased means.
Claim 4
Dependent Claim
44 words
Apparatus as defined in claim 2 wherein said biased means include a T-bar, and an elastic member coupling the T-bar to the frame; and wherein the motor responsive means include a cam coupled to the motor and a cam follower coupled to the T-bar.
Claim 5
Dependent Claim
39 words
Apparatus as defined in claim 3 wherein the clamping means are slidably connected to a pair of aligned slots in the T-bar, said slots being substantially perpendicular to the direction in which the T-bar is movable by the motor.
Claim 6
Dependent Claim
33 words
Apparatus as defined in claim 4 wherein said means for rotating the clamping means includes means, responsive to the thickness of the stack to be bound, for limiting rotation of the clamping means.
Claim 7
Dependent Claim
25 words
Apparatus as defined in claim 5 wherein said means for limiting rotation of the clamping means are supported by the means for supporting the substrate.
Claim 8
Dependent Claim
61 words
Apparatus as defined in claim 6 wherein said means for biasing the platens include another cam coupled to the motor and to two of the platens in the arrangement, said cams being aligned so that said another cam biases the two platens against the other side of the substrate when the means for limiting rotation limit rotation of the clamping means.
Claim 9
Dependent Claim
33 words
Apparatus as defined in claim 7 wherein the adhesive on the substrate is heat sensitive and said platens activate the adhesive when the platens are biased against said other side of the substrate.
