of the slidable mounting of the forward or front part

pressure within the roller varying shapes of the glue ap

both front and rear tracks 55 are similar to the front track
55 of the forward chain conveyor, but the rear track 57 of
the forward conveyor section is mounted in a sliding en
gagement with a lower ?xed section 67, and as clearly 45
shown in FIG. 17, the slidable portion of the track is
springdoaded by means of screw 61 and spring 63. The
pressure of the spring 63 against rigid shoulder 65 causes
a similar pressure to be exerted against movable section
57 of the track. Screw or shaft 61 is the guide ‘around
which the movable section is held.
Referring speci?cally to FIGS. 3 and 6, it will be seen
that sprocket wheels 54 and 56 at the feed-in end section
of the machine merely serve to guide the chain conveyor
systems with no motive force except that derived from the 55
motion of the chains themselves. These sprocket wheels
145, is employed to heat the ?uid in lower pot 140; which
in turn heats the glue 139 in the upper pot 138 and thus.
renders the glue suitable in viscosity for application. The
entire glue assembly is mounted on glue assembly sup
port 144, which consists of casting 152 which is movable
along guide and support rails 148 and 146 by means of
turn screw 150 with a handle 154. The purpose for slid
ably mounting the glue assembly is to permit the proper
positioning of the glue application holler under the back ,
of the book due to the different thickness of books which
can be handled. Upon actuation by switch assembly 11,
solenoid 167 exerts a pull force on plunger 169, which
causes arm 168 to effect movement in an arc of plates 66,
acting against pull-down spring 164, and since these plates
are journalled at the upper ends thereof to the shaft 130‘

the frame 188, the supporting structure for the crash

inside of the tubes 209 and 211. Beneath each of the
platforms 2G5 and 207 and around the lower ends of the
studs 213 and‘215 are springs 217 and 219. The function _,
of these springs is to return the rake 223 to its normal
position after the cycle has been completed, and this
normal position is just below the level at which the crash
is fed.
With further reference to the crash forming and applica
tion mechanism, it is to be noted that at each end of the
forming bar 222 and similarly at each end of the rear

engage a channel in the frame member 188. These studs

Attached to slide 336 secured to earn 272 at the
upper end of said slide is linkage 341. At the upper
end of this linkage 341 is fulcrum 338. Both pivot 344
and fulcrum 333 are secured to knife assembly 331 in
a manner similar in which linkage 216 and the upper
portion of slide 260 are secured to the knife assembly of
the crash station. At opposed ends of the knife assembly
are lugs 346 and 348 which are guided in frame 265 to
maintain an accurate and positive motion during the
movement of earns 27% and 272. The knife assembly
331 consists of knife holder 332 and knife 330. Also
mounted on shaft 276 and actuated by the engagement
of clutch 274 is crank assembly 286 to which is secured
rack 288 and pinion 296. This crank assembly through
the action of the rack and pinion actuates one way clutch

station comes to a halt as the selected length of crash is
fed out under the next book carried by the chain con
veyor system. Immediately as this next book engages the

up from the bottom of the books and extending to the end
of the machine. These forming bars hold the crash
against the sides of the book until the book is delivered
from the machine.
From the crash station, the books are moved along
to the next glue station 12, preparatory to the applica
tion of the backlining and headband material. This glue
is capable of starting the glue 1” from one end and ending
it 1/2” from the other end. Obviously by varying the
position of the ?ngers of the switch assembly an in?nite
the back of the books ever a predetermined and selected
around the brass pick-up roller 132. The book con
tinues on its uninterrupted movement across the glue
station while glue is applied to the back thereof by the
application roller. By precisely selecting and controlling
the position of the ?ngers of the two switches of the
switch assembly 11, it is possible to control with great
precision and accuracy the extent of the glue coverage
number of settings may be had with respect to the ex
tent of the glue coverage required for the crash to be
applied next. By this technique and control it is possible
to avoid the undesirable formation of beads of glue along
the edges of the book. When the trailing edge or back
end of the book passes the ?rst ?nger of the switch assem
bly, the ?nger snaps back into its neutral position and
breaks the series circuit which is the activating force for
the entire operation. With the circuit broken, the sole
noid releases the rubber application roller and permits
its return downwardly in its are around the brass pick-up
roller. The trailing edge of the book then passes the sec
ond ?nger of the switch assembly, and this ?nger, too,
snaps back into its neutral position but no changes occur
in the operation since the current has already been cut
off by the snap back of the ?rst ?nger of the switch as
sembly.
The book is now prepared for the next opera- .
tion, which is the application of the proper length of
crash material to the glue coating and impregnation on
the back of the book.
As described above, all of the stations are in an
activated condition due to the engagement of clutch 24,
and, of course, the next station, the crash station, is in
a similar active condition. The main power train to the
station, as explained above, is identical to the ?rst glue
station 8. At glue station 12 glue is again applied to
area controlled by the two-?ngered, series-connected, dou
ble switch similar to the switch at the ?rst glue station.
The continuously moving book is now ready for the sec
ond sheet applying phase of the operation, which is the
application of the backlining and headband together as
a composite structure in the preferred form. It is, of
course, possible to omit the headband or the backlining
but the versatility of the machine of the present inven
tion makes the application of both elements the preferred
manner of operation.
The entire backlining and headband station is activated
as described above by a switch similar ‘to the switch em
ployed at the site of the crash station. As the leading
edge of the book makes contact with ?nger 73 of the
switch 71, through a relay, two solenoids are given a
momentary impulse. Platform 304 raises up, and the
vacuum securing the precut sheet of backlining and head
band to the platform is broken enabling the sheet to
transfer to the back of the book at the moment of the
adhesive contact with the glue on the said back. The
book continues on its path to the next station while
the platform drops down. The second half of the cycle
now occurs which involves the feeding of another length
of backlining and headband material, as depicted in
FIG. 21 from separate feed rollers, the backlining 315
receiving a coating of glue along the edges thereof. Roll
crash station has been described above. The leading
edge of the book once again makes contact with a ?nger
73 of switch 71, whereby all of the operations of the

crash station are brought into action for one complete

contained therein that they are about 1A” above the bot

books pass over the said rollers. The wiping action of
the rollers results in a smooth back to the book. Any
glue which might be picked up by the rollers is washed
off in the water, and the roller is scraped clean after
emerging from the water. The amount of air within the
rollers also determines the amount of pressure applied
to the bottom of the books by the rollers. Following
the rollers are two rows of plastic ?ngers or strips 264,
each backed by a ?at spring, over which the bottom edges
of the book pass. These ?ngers are preferably made
