Abstract

Abstract An apparatus for binding stacks of sheets or leaves in which a horizontally fixed but vertically movable hot plate is pressed against the spine and a horizontally movable hot plate is displaced horizontally to clamp the flanks of the stack between vertical edges of the two hot plate parts. The clamping device for the stack is adjustable to hold different thicknesses of stacks by a mechanism connected to the movable hot plate part.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 130 words
IN AN APPARATUS FOR THE ADHESIVE BINDING OF A STACK OF SHEETS WITH A FOIL COATED WITH A THERMALLY ACTIVATABLE ADHESIVE BY DEPOSITING THE FOIL UPON A HOT PLATE HAVING A STATIONARY MEMBER HORIZONTALLY FIXED BUT VERTICALLY MOVABLE AND A MOVABLE MEMBER HORIZONTALLY DISPLACEABLE RELATIVE TO THE STATIONARY MEMBER TO RECEIVE AN EDGE OF THE STACK BETWEEN SAID MEMBERS AND, UPON VERTICAL DISPLACEMENT OF SAID HOT PLATE, TO FOLD THE FOIL AROUND SAID EDGE, THE IMPROVEMENT WHICH COMPRISES: CLAMPING MEANS ENGAGEABLE WITH SAID STACK AND INCLUDING TWO PARTS SEPARABLE BY THE WIDTH OF SAID STACK; AND MEANS FOR COUPLING AT LEAST ONE OF SAID PARTS WITH SAID MOVABLE MEMBER FOR POSITIONING SAID MOVABLE MEMBER IN SPACED RELATION RELATIVE TO SAID STATIONARY MEMBER IN DEPENDENCE UPON THE SPACING OF SAID PARTS.
Claim 2
Dependent Claim 130 words
IN AN APPARATUS FOR THE ADHESIVE BINDING OF A STACK OF SHEETS WITH A FOIL COATED WITH A THERMALLY ACTIVATABLE ADHESIVE BY DEPOSITING THE FOIL UPON A HOT PLATE HAVING A STATIONARY MEMBER HORIZONTALLY FIXED BUT VERTICALLY MOVABLE AND A MOVABLE MEMBER HORIZONTALLY DISPLACEABLE RELATIVE TO THE STATIONARY MEMBER TO RECEIVE AN EDGE OF THE STACK BETWEEN SAID MEMBERS AND, UPON VERTICAL DISPLACEMENT OF SAID HOT PLATE, TO FOLD THE FOIL AROUND SAID EDGE, THE IMPROVEMENT WHICH COMPRISES: CLAMPING MEANS ENGAGEABLE WITH SAID STACK AND INCLUDING TWO PARTS SEPARABLE BY THE WIDTH OF SAID STACK; AND MEANS FOR COUPLING AT LEAST ONE OF SAID PARTS WITH SAID MOVABLE MEMBER FOR POSITIONING SAID MOVABLE MEMBER IN SPACED RELATION RELATIVE TO SAID STATIONARY MEMBER IN DEPENDENCE UPON THE SPACING OF SAID PARTS.
Claim 3
Dependent Claim 58 words
The improvement defined in claim 1 wherein said means for coupling at least one of said parts with said movable member includes a mechanism for displacing said movable member away from said stationary member, a stop engageable with said mechanism for limiting the displacement of said movable member and means operatively connecting said clamping means with said stop.
Claim 4
Dependent Claim 46 words
The improvement defined in claim 2 wherein said clamping means includes a first spindle provided with a thread and rotatable to space said parts apart, said mechanism including a second spindle rotatable for positioning said stop, and transmission means operatively connecting said spindles for joint rotation.
Claim 5
Dependent Claim 71 words
The improvement defined in claim 3 wherein said mechanism further comprises a body connected to said movable member and engageable with said stop, a crank cam rotatable for displacement of a rod relative to said body, and friction clamp means in said body engageable with said rod to lock said body with said rod until said body engages said stop and thereafter enabling relative displacement of said rod and said body.
Claim 6
Dependent Claim 52 words
The improvement defined in claim 1 wherein said means for coupling at least one of said parts with said movable member includes a flexible element engaging said movable member and a pulley connected to said clamping means for displacing said movable member, said apparatus further comprising means for reciprocating said movable member.
