Abstract
Abstract Apparatus for adhesively binding stacks of pages with a cut portion of adhesive strip has a form forming a trough arrangement to accommodate the back of the stack of pages to be stuck comprising a form bottom and two form walls disposed thereon. The loose pages are jogged into flush condition on an abutment plate and then held in a clamp. After the portion of adhesive strip has been fed into a position covering the trough arrangement, the back of the stack pages is shifted laterally and inserted into the form arrangement and retracted from the form after the portion of adhesive strip has been stuck to the back. The abutment plate is disposed parallel beside the trough arrangement at a higher level than the form walls and the clamp is mounted on a slide guide means which is movable parallel and normal to the plane of the form bottom. The parallel movement of the clamp extends from the abutment plate location to above the trough arrangement and the normal movement of the back of the stack of pages extends from the higher lever of the abutment plate to the form bottom.

Claim 1
Independent Claim
201 words
Apparatus for adhesively binding stacks of loose pages with an adhesive strip comprising: a form providing a trough arrangement adjustable to the back of the stack of pages to be bound, said form including a form bottom and two form walls disposed thereon; an abutment plate disposed parallel to the form bottom and to the walls of said trough arrangement at a higher level than said form walls, said plate serving to support a loose stack of pages to be jogged into flush condition against said plate; clamping means having an open condition to receive the loose stack of pages and a closed condition to clamp the stack of pages, said clamping means being mounted on a slide guide means which is movable parallel and normal to the plane of said form bottom, said parallel movement of said clamping means extending from the location of said abutment plate to a location above said trough arrangement and said normal movement of the back of the stack of pages clamped in said clamping means extends from said higher level of said abutment plate to said form bottom; and means for retaining a portion of adhesive strip in a position covering said trough arrangement.

Apparatus for adhesively binding stacks of loose pages with an adhesive strip comprising: a form providing a trough arrangement adjustable to the back of the stack of pages to be bound, said form including a form bottom and two form walls disposed thereon; an abutment plate disposed parallel to the form bottom and to the walls of said trough arrangement at a higher level than said form walls, said plate serving to support a loose stack of pages to be jogged into flush condition against said plate; clamping means having an open condition to receive the loose stack of pages and a closed condition to clamp the stack of pages, said clamping means being mounted on a slide guide means which is movable parallel and normal to the plane of said form bottom, said parallel movement of said clamping means extending from the location of said abutment plate to a location above said trough arrangement and said normal movement of the back of the stack of pages clamped in said clamping means extends from said higher level of said abutment plate to said form bottom; and means for retaining a portion of adhesive strip in a position covering said trough arrangement.
Claim 3
Dependent Claim
35 words
Apparatus according to claim 1, wherein the tops of the form walls, which are remote from the form bottom, are covered over by guide bars which accommodate the respective portion of adhesive strip between them.
Claim 4
Dependent Claim
35 words
Apparatus according to claim 2, wherein at their sides which are towards the tops of the form walls the guide bars are each provided with a respective recess for suitably accommodating the adhesive strip portion.
Claim 5
Dependent Claim
13 words
Apparatus according to claim 3, wherein the recess is formed as a groove.
Claim 6
Dependent Claim
35 words
Apparatus according to claim 4, wherein at their ends at which the adhesive strip portion is inserted, the guide bars are provided with an upwardly bent portion which enlarges the recess in a funnel-like configuration.
Claim 7
Dependent Claim
25 words
Apparatus according to claim 1, wherein the form walls are provided with bevels which enlarge the configuration of the trough arrangement in a funnel-like shape.
Claim 8
Dependent Claim
22 words
Apparatus according to claim 6, wherein the bevels taper down in the same direction, in the longitudinal direction of the form walls.
Claim 9
Dependent Claim
40 words
Apparatus according to claim 6, wherein the tops of the form walls extend at a slightly inclined angle relative to the form bottom, along the longitudinal direction thereof, and in the same direction, in the case of both form walls.
Claim 10
Dependent Claim
69 words
Apparatus according to claim 8, wherein at least one form wall is mounted to be laterally displaceable and said form wall is connected to a displacement mechanism for pulling the form wall away from the stack of pages before the stack of pages is inserted and before it is withdrawn, and for causing, between said phases in displacement, the form wall to be pressed against the stack of pages.
Claim 11
Dependent Claim
28 words
Apparatus according to claim 9, wherein, for the purposes of using adhesive strip portions which bear a fusion-type adhesive, the form bottom is provided with a heating means.
Claim 12
Dependent Claim
32 words
Apparatus according to claim 10, wherein for the purposes of restricted heat transfer, the form walls bear against the form bottom by way of projections which are distributed along the form walls.
Claim 13
Dependent Claim
21 words
Apparatus according to claim 5, wherein the guide bars are held at a spacing from the tops of the form walls.
