13 Claims.

Our invention consists in a novel and eflicient method of providing book bodies with hinge strips, said method including the following steps: advancing successive book bodies along a suitable support; causing the edges of a wide'tape to overlap the opposite sides of the advancing book bodies; securing the overlapping edges to the book bodies; slitting the wide tape into two narrow tapes; and severing the narrow tapes between successive book bodies to form the hinge strips therefor.

Our invention more specifically comprises one or more of the following additional steps: gumming one face of the wide tape along its opposite edges; causing one gummed edge to overlap and adhere to the under sides of the advancing book bodies; guiding the book bodies; turning the wide tape to cause its other gummed edge to overlap and adhere to the upper sides of the advancing book bodies; drilling the overlapping edges, and book bodies, andstitching them together; and gluing the stitches.

A machine for carrying out our method is shown and described herein, such machine forming the subject matter ofour copending application filed of even date herewith, its Serial No. being 365,592.

The supporting table is denoted by I. The magazine for supplying the book bodies is denoted by 2. The intermittently moving endless conveyor is denoted by 3.- and it is provided with blocks 4 positioned to advance successive book bodies in spaced relationship from the magazine into positions for the several operations thereon.

The support for the roll of wide tape which is later to form the hinge strips for the book bodies, is denoted by 5. A means 6 is provided for gumming one face of the wide tape 7 along the opposite edges thereof, said gummed edges being denoted by 8 and 9.

A longitudinally disposed guard H3 is located in the magazine 2 in position to prevent the under side of the bottom book body from contacting with the gummed edge 8 of the wide tape 'iuntil the book body has left the magazine.

left the magazine, is denoted by II. The means for turning the tape may comprise a rotary brush I2, a curved guide .I3 and the spring pressed finger I4, which finger coacts with the former bar i I to hold the wide tape in its turnedover position as it approaches the stitcher.

The front gage bar I5 is adjustable toward and away from the back gage bar for different widths of book bodies. The back gage bar is herein shown as made in two aligned separated sections I6 and Il. End supports I8 and I9 are provided for the first section I3 of the back gage bar, the end support I9 uprising from the table I. The second back gage bar section I! is supported only at one end, in the present instance by a downward branch 2I secured to the table supporting frame 22.

The former bar II is adjustably supported at one end by the magazine 2 and at the other end by the cutter support to be hereinafter described.

The stitcher in the present instance includes bottom and top drills 23 and 24, the needle and their usual operating mechanismswhichserve to cause the bottom drill 23 to out holes upwardly part way through the book bodies and their associated Wide tape, and the top drill 24 to complots the holes, said needle 25 operating through said holes with its thread to stitch the overlapping edges of the wide tape to the book bodies as the holes are completed.

The means for slitting .the wide tape 1 into upper and lower tapes after the overlapping edges of the wide tape have been stitched to the book bodies, comprises a slitting knife 26 projecting rearwardly from the former bar II.

A guillotine cutter support 21 is mounted on the table I, the knife 28 of which cutter is operated at predetermined intervals by the stitcher to sever the wide tape between successive book bodies to form hinge strips therefor. Means controlled by the advance movement of the book bodies are provided for permitting the operation of the knife at the desired intervals, said means comprising the following elements: a trip lever 29 is held normally depressed by contact with the under sides of the book bodies and permitted to rise into the space between successive book bodies when opposite the same. This trip lever 29 is provided with a pinion 30 which meshes with a rack 3| carrying a cam bar'32. This cam bar 32 is provided at its upper end with a cam 33 so that when the cam bar is lifted by the upward swing of the trip lever into the space between two successive book bodies the said cam will engage a cam 34 .on a spring retracted latch 35 carried by the shank 33 of the knife 28 to force the latch into a slot 31 in the reciprocating bar 38 operatively connected to the stitcher. The downward movement of the bar 38 will cause it to engage the latch 35 and thereby move the knife 28 downwardly between the adjacent ends of the back gage bar sections I6 .and I1 and through a slot 39 in the table I.

Springs 40 may be used to hold the tape severing knife 23 in its raised inoperative position. A spring 41 is provided for yieldingly holding the trip lever 29 in its raised position.

Means may be provided for gluing the exposed stitches along one of the hinge strips of each book body, said means comprising a glue fountain 42 and its glue applying roll 43, said roll being located in the present instance in position to project upwardly through a slot 44* in the table. This gluer may be driven from the endless conveyor 3 through the train of gears 44, 45, 4B (sh-own in Fig. 2).

Pressure means may be applied to the upper sides of the book bodies as they pass from the magazine 2 to the delivery end of the endless conveyor 3, said means comprising the pressure roller 41 at the magazine, the pressure rollers 48 located at the cutter and the pressure rollers 49 located at the gluer.

A modified form of the trip lever 59 (shown in Figs. 23 and 24) may be provided with an extension foot 5| .to accommodate the trip lever to successive book bodies having longer spaces between them.

To by-pass the free portion of the lower narrow .tape around the end support I9 of the back gage bar section I6 the table I may be provided with an open ended curved slot 52, through which the said free portion of the lower narrow tape is passed beneath said support I9.

In operation, the wide tape as it passes from the supply roll carried by the support 5 is led through the gummer 6 to gum one face of the tape along its opposite edges. The tape is then led to and along the table I with one gummed edge passing through the magazine 2 between the endless conveyor 3 and the guard I0. After the bottom book body is advanced from the magazine by the endless conveyor the under side of the ibOOk body will contact with and adhere to the gummed edge 8 of the wide tape. It will be seen that the wide tape is thus advanced by the movement of the book bodies. As the book bodies reach the turning mechanism the transversely disposed rotary brush I2 serves to turn the wide tape around the bar I I sufficiently to cause the tape to be engaged by the curved guide I3 and completely turned over the former bar to cause the gummed free edge 9 of the wide tape to overlap and adhere to the upper sides The book bodies with the turned-over wide tape are then advanced by the endless conveyor 3 into position to be drilled and stitched. The wide tape is then slit by the knife 25 into two narrow tapes. The free portion of the lower narrow tape is passed through the slot 52 beneath the back gage bar support I9 to by-pass the said free portion around said support. After the slitting operation the narrow tapes and the line of stitching are severed between successive book bodies, said severing mechanism operating only when the free end of its controlling trip lever 29 is permitted to swing upwardly into the space between two successive book bodies. It is understood that the trip lever 29 is held depressed by its contact with the under sides of the advancing book bodies except when the spaces between successive book bodies come opposite the free end of the trip lever.

The book bodies are then advanced to a position where the exposed stitching along the under side hinge strips may be glued in the usual manner. to lock the stitches.

It will be understood that the former bar is vertically adjustable to center it with respect to the Wide tape irrespective of the width of the book bodies. It will also be understood that the back gage bar sections may be either vertically adjustable or replaceable by other bar sections of a different width to center the back gage bar with respect to different widths of book bodies.

While we have shown the stitcher as a sewing machine, it is evident that we wish to cover other means, such as staplers, if so desired, without departing from the spirit and scope of our invention.
