-Application March 24, 1937, Serial No. 132,778 In Great Britain March 30, 1936 8 Claims.

This invention relates to the binding of booklets, catalogues and other publications on wire stitching machines and is more particularly concerned with saddle stitched booklets and the like.

In wire stitcher-feeding machines for inserting and stitching saddle-stitched work, sections of folded paper, hereinafter referred to as signatures, are placed on the stitching machine at a number of feeding stations, each of which is provided with a saddle bar for receiving the signatures, and a conveyor chain gathers the signatures together from each station and feeds the gathered signatures, with their covers, to a stitcher head where wire stitches are inserted through the backs of the booklets or the like thus formed.

Booklets and the like bound and s titched in this way have the disadvantage that the covers are liable to be torn off, since they are only secured by the wire stitching. 'One of the objects of the present invention is to overcome this disadvantage by applying a hot or cold a the back and/or sides of one or more dhesive to of the inserted signatures, and essentially the outer signature, when travelling or stationary on the-wire stitching machine and prior to the cover being laid on the gathered signatures, whereby the cover is adhesively secured automatically to the back of the outer signature in addition to being stitched thereto with wire stitches.

Although the primary object of the invention is to secure the cover to the outer section of the booklet more, securely than hitherto,

it will be clearly understood that each or any of the inserted signatures may be adhesively secured to one another in the same way before the wire stitching operation is effected.

In order that the inventiorrmay be better understood one particular embodiment thereof will now be. described with reference to the accompanying drawing, but it must be understood that the construction and arrangement of the embodiment illustrated may be many respects without departing from and scope of the invention.

In the drawing Figure 1 is a side parts, in varied in the spirit elevation showing the conveyor, feeding stations and a stitcher head of a wire stitching machine provided with adhesive applying means ac cording to the invention; and Figure 2 is a sectional view of a modified part of the adhesive applying means.

Referring to the drawing the machine comprises a plurality of saddle bars 2 for receiving the signatures 3 which are to be collected together and bound into book form and a conveyor chain 4 for collecting the signatures and conveying them to a device, indicated generally at 5, for applying adhesive to the back and/or sides of the outer signature and finally to head 5 where wire stitches are inserte a stitcher d through the backs of the booklets after the cover has been laid on. The adhesive applying device in its simplest form comprises a container 1 for the adhesive rigidly mounted above the conveyor chain 4 and provided with a roller'8 rotatably' :mounted in bearings in the walls of the container I and projecting through an aperture in the bottom of the container. The under side of the roller 8 lies in substantially the same horizontal plane as the upper edge of the saddle bar 510 2 or slightly below this plane so as to ensure that the back or folded edge of the signature contacts with the roller as it is slidden 01f the saddle bar. The roller 8 may be plain or may be grooved, as shown on an enlarged scale in Figure 2, whereby the sides as well as the backs of the signature 3 are coated with adhesive'as will be. clearly seen from the figure.

It is an essential feature of the invention that adhesive should be applied to the back and/or sides of the outer signature, that is the signature immediately adjacent the cover, so that an adhesive applying device 5 must necessarily be located between the last pair of saddle bars-2, that is to say between the saddle bar upon-whichim; the last signature is laid and that upon" which the cover is laid. In certain circumstances, however, it may be desirable for each of the inserted signatures to be adhesively secured together and in this case an adhesive applying device 5' must 13.30 be provided between each pair of saddle bars.

In operation the individual signatures, which are to be bound into book form, are placed on the saddle bars 2 from which they are removed onto the conveyor 4 by pusher members 9 carried by 2:35 the conveyor in known manner. The conveyor then carries the collected groups of signatures under the roller 8 which applies a coating of adhesive to the back and/or sides of the outer signature, as described above, whereupon the groupciio of signatures are carried past the last saddle'bar from which the cover of 'the booklet is removed by the pusher members of the conveyor onto the adhesively treated outer signature of the group. The complete booklet is then carried by the 0011-3545 veyor to'suitable stitcher mechanism 6 where the booklet is stitched with wire stitches in well known manner.

What I claim and desire to secure by Letters Patent is:- P
