This invention relates to machines for making box blanks, and, more particularly, to

machines for making foldablc wirebound boxblanks.

Among other objects, the invention is intended to provide certain improvements contributin g to the eliicienc and economical operation of such machines, and broadening their field of operation to include the manufacture of types of box blanks not heretofore produced on box blank machines; said improvements being hereinafter particularly described and claimed.

One illustrative embodiment of the invention is shown in the accompanying drawings, in which:

Fig. 6 is sectional view of the box blank taken on the line 66 of Fig. 5.

Fig. 7 is a sine elevation of the box blank of 5 with the exterior cleats omitted for clearness of illustration.

Fig. 8 is an end elevation of the box blank of Fig. 5.

The illustra ive machine consists generally of positioning and feeding means for the box parts, stapling" mechanism adapted to apply binding wire to the box parts, means to provide slack in a binding wire between successive staples at certain points, means to sever the binding wire between box blanks, and means to strip or remove the finish-ed blanks from the positioning and feeding means; the several operating elements being ort d by the usual supporting frames and cross-bars.

The detailed description of the machine will be clarified by reference to one illustrative product of the machine which is shown in Figs. 58 inclusive. As there shown, the box blank consists of four separate foldably related sections, each section comprising a sheet or sheets of side material a, an interior oleat b atone end of the side material, and an exterior cleat 0 at the other end of the side material; the several sections being foldably connected by binding wires d, d, d secured to the several sections by staples e. The several sections may be located close enough together to produce, when folded, a tight cornered box with the wires tensioned over the corner edges. Th s result may be accomplished by spacing adjacent edges of the side material a distance substantially equal to or slightly less than the thickness of the side material. If an open corner box is desired the sections of side material may be spaced apart appropriate distances to provide the desired corner openingsin the finished box.

lit will be noted that, binding, wire d 0011- tacts with the side material in line with the interior cleats Z) and is stapled to the side material and the interior cleats by staples which pass through the side material and into or through the interior cleats; that binding wire cl contacts with the side material and is stapled thereto by staples which pass through the side material and are preferably clinched 011 the underside; and that binding wire 03 contacts with the exterior cleats '0 and is stapled thereto by staples which preferably pass through the exterior cleats and the side material and are clinched on the underside of the side material. Additional wires (Z may be applied ifneeded.

As best shown in Fig. 6, slack may be provided in binding wire 03 over adjacent ends of exterior cleats c to facilitate folding the blank sections into box form. Such slack is shown at S in Fig. 6. To lessen the amount of slack wire required at said points, grooves 9 maybe provided in the ends of exterior cleats c to receive and hold the binding Wire cl when the blank is folded into box form. It will be understood, however, that in certain forms of box no such slack wire is required or provided.

The means for positioning and feeding the box parts is best shown in Figs. 2, 3 and l. As there shown, interior cleats b are positioned and fed in a channel-shaped endless conveyor chain 1 supported and guided by a stationary channel 2 secured to cross-bars at either end of the machine. The interior cleats are positioned against longitudinal movement by positioning blocks 8 adjustably secured to a flange on chain 1. Each section of side material a is supported at one end by an interior cleat b. The other end of each section of side material is preferably support ed by a stationary angle-guide 4 supported by cross-bars at either end of the machine. Angle-guide land conveyor chain 1 are provided with outer flanges extending high enough to prevent the side material from shifting sidewise of the machine. The several sections of side material are ")ositioned longitudinally of the macnme by positionmg fingers 5 earned by bloc 3 and by pos1- 'tioning fingers 6 carried by blocks 7 adjustably secured to an endless chain 8. Endless chain 8 lies adjacent angle-guide 1 and is supported and guided by a fixed channel 9 secured to cross-bars at either end of the machine. Bloc as 7 extend over the top of the cleats 0 away from blocks 7 and to insure the correct positioning of the exterior cleats dur ing the stapling operation, positioning arms 10 and 11 are providedtoengage each exterior cleat as it approaches the stapling plane and press it down on to the side material and over against blocks 7 and hold it in such position during the stapling of such cleat. Arms 10 and '11 are hung from brackets 12'which are secured to the side of fixed channel 9. Arm 10 is yieldingly pressed against the top of each exterior cleat by springs 13, the forward end of the arm 10 being beveled to permit the cleat to be forced under the arm 10. Arm 11 is yieldingly pressed against the inner side of each exterior cleat bysprings 14-, the forward end of the arm 11 being beveled at the side adjacent the cleat to permit the cleat to be forced past the arm 11.

sprocket wheels at either end of the machine and are fed in any suitable manner to pre sent the box parts to the stapling mechanism. In the illustrative machine the feed chains are with a continuous motion and the stapling mechanism operates on the moving work at controlled intervals in the manner illustrated and described in United States patent to O. C. Thompson, No. 1,738,806 dated Dec. 10, 1929 reference to which is hereby made for a detailed description of the chain feeding mechanism and the stapler controlling mechanism.

The stapling mechanism for applying the binding wires to the box part-s consists of a plurality of stapling headsone for each binding wire to be appliedwhich operate in unison to form staples from staple stock wire automatically fed thereto and to drive the staples over the. binding wire into the box parts. The individual stapling heads may be of the type shown in United States patent to O. C. Thomps lilo. 1,669,383, dated May 8, 1928, but their size and arrangement is varied to provide for stapling operations in different horizontal planes. For example, the stapling heads numbered 15 and 16 in 2, which apply the binding wires d and d, operate to drive staples in the horizontal plane of the upper surface of the side material, while the stapling head numbered 17 in Fig. 2, which applies the binding wire d,

operates to drive staples in the horizontal plane of the upper surface of the exterior cleats. Thus, as best shown in Fig. 2, the

lower extremit T of sta 71111 head 17 is 10- cated in a-higher horizontal plane than are the lower extremities ofstapling heads 15 and 16.

To provide the slack S in binding wire d when desired, the fingers 6 which lie between adjacent exterior cleat ends, extend above the upper surfaces of the exterior cleats a sufiicient distance so that when a finger 6, whicl is fed to the stapling head 17 beneath and in line with wire d, reaches the stapling plane, the wire engages finger 6 and is held thereby above the upper surfaces of the exterior cleats (see Fig. 3), thus producing the slack S shown in Fig. 6. The positioning arm 10 and a presser bar 18 which may be secured to the back plate of stapler head 17 assist in producing a uniform slack by holding the side material and exterior cleats down in angle-guide 4.

The stapling operations may be controlled in the manner shown in said Thompson Patcnt No. 1,738,806, to prevent any stapling operation during the time a finger 6 is passing beneath stapling head 17.

After a box blank has been wired, and while the stapling mechanism is applying wire to the next succeeding box blank, the wires between said box blanks may be severed by wire severing mechanisms 19. Said all if; Ii

wire severing mechanisms maybe of the type shown in United States patent to O. C.

of the machine. The other end of stripper bar 20 is supported in its raised position by an arm 25v pivoted to the raised end of bar 20 and bolted to the supporting bar 21; said arm 25 being providedwith a plurality of bolt holes 26fto permit adjustment in the elevation of the raised end of'the stripper bar.

In the illustrative machine, the conveyor chains 1 and 8 which feed the box parts beneath the stapling mechanism are advanced continuously at substantially a uniform speed, and the stapling heads are mounted on a carriage which reciprocates over. the mov-' clinches the ends of the staples which are driven through the side material. v

To resist the thrust of stapling head 1 and to clinch the ends of the staples which are driven through exterior cleats and the side material' a, a clincher block 29 is secured to 'the cross-oar 28 directly beneath stapling head 17. Clincher block 29 extends upward through an opening formed in stationary angle-guide at, said opening being of suiiicient' length to permit block 29 to reciprocate with the stapler carriage, and the upper surface of block 29 beingsubstantially flush with the upper surface of angle-guide l. Such an arrangement produces a better clinching operation than could be obtained by clinch- "ing the staple ends against the stationary angle-guide l. r i

The binding wire stock and the staple wire stock may be supported and fed 1n the manner shown in said Thompson Patent No.

The set-up and operation of the machine is as follows: 7 V

Positioning blocks 3 carrying fingers 5 are secured to conveyer chain lthe proper distances apart to 'POSl'tlOIl the interior cleats 1 quired and the sheets of side material. Positioning blocks 7 carrying fingers 6 are secured to conveyor chain 8 opposite blocks 3 on chain 1, the fingers 6 of the three intermediate blocks 7 being high enough to produce the rea'n'iount of slack in the wire over adjacent exterior clea; ends when such slack is desired. The stapl control mechanism is th a set in the m nier disclosed in said 1 'ent No. 1,?33,806, to locate the staples where dedred in the work. The machine is then started and place the interior cleats in chain 1 between blocks 3, lay the sheets of side material on the interior cleats between fingers 5 and on the stationary angle-guide t between fingers G.- lilxterior cleats c are then placed on the side material between lingers 6 and against blocks I n, "we

it will be understood that the invention is not limited to the particular embodiment 1 thereof shown herein for illustration, and

that all the inventive features need not be i -v be placedin' the maerior cleat and Presser wire between sec During the operations the bars and the wire severing or channel may be substituted for the stationary angle guide 4.
