Abstract
Abstract Apparatus for feeding a cut portion of adhesive strip for sticking the back of a book block or the like has a path for longitudinally guiding the adhesive strip drawn from a roll. In the path, a severing blade is located above a working table upstream from a deposit means for the portion of adhesive strip. Laterally of the working table and parallel to the deposit means is a slide guide having a slide from which projects a gripper having a clamp for gripping the end of the adhesive strip which is held in a waiting position at the cutting location of the severing blade. The slide guide extends from the region of the severing blade to beyond the end of the deposit means and stops are provided in the course of the slide guide means for stopping the slide.

Claim 1
Independent Claim
307 words
Apparatus for feeding a cut portion of adhesive strip for sticking the back of a book block comprising: a working table having means defining a path for longitudinally guiding an adhesive strip across said table; a holder for a roll of adhesive strip mounted at one end of said path; a severing blade arranged above said working table in the course of said path; deposit means for the portion of adhesive strip on said table; slide guide means having a slide arranged parallel to said deposit means disposed laterally along one side of said working table, said slide guide means extending from the region of said severing blade to a location beyond the end of said deposit means; a gripper supported by said slide guide means having a clamping means for gripping the end of the adhesive strip to be held in a waiting position at the cutting location of said severing blade; a first stop for stopping said slide in the course of said slide guide means, said first stop being operative to stop said slide in an initial position in which said clamping means extends beyond said cutting location for a distance such that the end of the adhesive strip can be gripped by said clamping means; a second stop for stopping said slide in the course of said slide guide means, said second stop being operative to stop said slide in a severing position at which the required length of adhesive strip has been drawn past said cutting location, said slide being releasible from said second stop for said slide to over run said second stop; a third stop for said slide mounted to stop said slide in an end position in which the leading end of the adhesive strip portion is located at the intended end of the book block to be stuck.

Claim 3
Dependent Claim
26 words
Apparatus according to claim 1, in which the second stop is adjustably locatable for adaptation to the length of the respective book block to be stuck.
Claim 4
Dependent Claim
31 words
Apparatus according to claim 2, in which the second stop is mounted on a longitudinally displaceable, arrestable bar which is arranged parallel to the slide guide means on the working table.
Claim 5
Dependent Claim
58 words
Apparatus according to claim 3, in which the first stop and the slide have parallel end faces which face towards each other and which bear against each other in the initial position, and which at the same time form the contact faces for a book block which is laid therebetween, for the purposes of setting the second stop.
Claim 6
Dependent Claim
18 words
Apparatus according to claim 1, in which the third stop is constructed so that it can be overrun.
Claim 7
Dependent Claim
116 words
Apparatus according to claim 5, in which the gripper comprises a bottom plate and a clamping plate which is movable relative to the bottom plate and which is urged by a spring loading against the bottom plate, and the two plates project out of the slide transversely with respect to the slide guide means and each have a respective angular tongue portion, the tongue portions being directed into the path in the opposite direction to the feed direction of the adhesive strip and the ends of the tongue portions forming the clamping means, there being a hand lever arranged on the slide to act on the clamping plate for the purposes of opening the clamping means.
Claim 8
Dependent Claim
24 words
Apparatus according to claim 6, in which a retractable slider member is mounted on the slide and cooperates with the second and third stops.
Claim 9
Dependent Claim
58 words
Apparatus according to claim 7, in which the slider member is suspended on the hand lever in which a way that, upon actuation of the hand lever in one direction the clamping means is opened and when the hand lever is actuated in the opposite direction both the clamping means is opened and the slider member is retracted.
Claim 10
Dependent Claim
106 words
Apparatus according to claim 8, in which the bottom plate of the clamping means is provided with a wire spring which extends longitudinally of the respective tongue portion and which, when the clamping means is in a closed condition, extends through a slot in the clamping plate side of the clamping means and holds the respective end of the adhesive strip between itself and the bottom plate side of the clamping means and, when the clamping means is opened and the adhesive strip is entrained by the clamping plate side of the clamping means, strips the end of the adhesive strip from said clamping plate side.
