seams and to extend beyond said hooks and be included between the lapped portions of the seams. The present invention resides in the provision of novel apparatus for forming such packing strips and adhesively uniting them with edge portions of successively presented container body blanks so that as said blanks are formed into containers the packing strips will be positioned in the side seams as stated. An example of a form of container including a packing strip in the solderless side seam is illustrated in U. S.
Letters Patent 2,171,711, issued to Walter G.
Plumb and Herbert Schrader on September 5, i939.
An object of the invention is to provide an apparatus of the character stated wherein the container blanks are' successively presented at the strip applying station, and in which means is included at the strip applying station for punch forming individual packing strips and adhesively aflixing them to the successively presented blanks.
Another object of the invention is to provide an apparatus of the character stated wherein the packing strips are punch formed from a web of paper bearing a heat fusible adhesive on one face thereof, and means is provided for applying heat 0 the strips to render the adhesive thereon tacky and also means for pressing the tacky faces of the formed and heated strips in proper position against the individually presented blanks.
Another object of the invention is to provide an apparatus of the character stated wherein the surfaces of the strips attached to said puncheswhile they are passing to said applying position.
Another object of the invention is to provide an apparatus of the character stated in which the punches serve to form the strips to carry them to the applying position, and to press the tacky strips against the successively presented blanks at said applying position.
Another object of the invention is to provide an apparatus of the character stated in which is included means for detecting the absence of a packing strip on any given successively presented container blank and for ejecting such defective or incomplete blanks from the apparatus.
With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by following the detailed description, the appended claims, and the several views illustrated in the accompanying drawings. 1

Figure 11 is a fragmentary end view illustrating the paper web feeding and cutter bar aligning mechanisms.
Figure 12 is a detail vertical section taken on the line l2-l2 on Figure 11.
Figure 13 is a vertical longitudinal section taken on the line "-43 on Figure 11.
Figure 14 is a vertical cross section taken on the line "-14 on Figure 12.
Figure 15 is a plan view of the parts illustrated in Figure 12. r
Figure 16 is an enlarged fragmentary sectional view taken on the line lG-IG on Figure 12.
Figure 17 is an enlarged fragmentary vertical cross section taken at the detector station.
Figure 1 is an enlarged side elevation illustrating the parts at the detector and blank ejector which has. had a packing strip applied thereto and which has been slitted and notched in the body making machine. t Figure 23 is a view similar to Figure 22 and illustrates the same blank after the seam hooks have been bent into position for being subsequently interlocked in the formation of the side seam.
Figure 24 is an enlarged fragmentary cross sectional view illustrating the hooks of the blank shown in Figure 23 interlocked prior to the final bumping and completion of the seam.
Figure 25 is a view similar to Figure 24 illustrating the relation of the hooks in the finished seam.
Figure 26 is a view similar to Figures 24 and 25, the section being taken at the position of the lapped portion of the seam rather than through the interlocked hooks.
In the example of embodiment of the invention herein disclosed the invention i shown as embodied in one section of a container body making machine. This type of machine is well known and an example of such a body maker is dis-' closed in the U. S. Letters Patent to Troyer et al., 1,772,820, issued August 12, 1930.
In the type of body maker referred to, can body blanks are withdrawn one by one from a supply stack and are fed intermittently, or station to station, along suitable supporting ways. At one station the blanks are fed from a low level laterally through grain breaking roll and are returned .by these rolls to a higher level along which they are again fed' step by step. At another station the lateral edges of the blanks are notched and slit in the manner illustrated in Figure 22. At another station the edge hooks which are to be interlocked in the formation of a lock and lap seam are bent in the manner lower center guide members I2. See Figures 1 indicated in Figure 23. At another station the blanks are shaped about a forming horn in a manner for bringing the hooks thereof into interlocking relation as illustrated in Figure 24, and at this same station a bumping steel engages the hooks and serves to finish the seam in the manner illustrated in Figure 25.
The particular mechanisms forming the basis of the present invention are adapted. to apply packing strips to the blanks in the position illustrated in Figure 22 so that said strips will be embodied as packing elements in the side seams in the manner illustrated in Figures 24' through 26. The mechanism of the present invention also includes detecting and ejecting devices effective to eject from the machine any blanks which have not had packing strips affixed thereto.
Figure 1.
The mechanisms forming the basis of the present invention are mounted between the grain breaking rolls and the position at which the body blanks arenotched and slit. The improved body making machine as a whole in which thi invention is to be embodied may be said to comprise three distinct sections, namely, a section such as is herein disclosed and which includes the packin strip applying mechanism, the blank ejecting devices, and suitable mean for feeding the blanks and also for grain breaking the same after the usual custom, a second section which will. comprise a standard form of body maker from the position of the notching mechanism on through the forming station, and a third section comprising a flanging mechanism for fianging the ends of the formed can bodie immediately after they are formed. As before stated the second section of this machine is conventional, and this third section, the fianging machine, is disclosed in a co-pending application filed by Paul E. Pearson on December 27, 1940, identified by Serial No. 371,975.
The herein disclosed first section of the improved body making machine, preferably assembled as an attachment to the remaining standardized and conventional parts of the body making machine, includes a base 5 which maybe a separate base extending throughout this particular section of the machine only, or it may be an extension from the base of the main or body forming section of the machine. The attachment includes a bed! forming an extension of the bed of the main section of the machine and which is supported on frame legs I. The bed I supports side housing members 8 which form extensions of the like portions of the main section of the machine and are arranged-in parallel spaced relation in the usual manner. The housing members 8 support suitable slideways or guides 9, 90. for the lateral edges of the blanks Ill which are fed'along the ways step-by-step, or station-by-station, by the conventional reciprocable feed bars II in the manner well known to all workers in the art familiar with the socalled 4-13 body maker herein referred to. The blanks ID are fed between the usual upper and and 2.
The machine attachment frame supports a blank stack is from which blanks are individually withdrawn from the bottom in the usual manner by a suction cup i4 mounted at the upper end of a vertically reciprocable carrier I5 which is crank and link connected as at 16 with a thrust arm i'l in turn connected with a crank 18 driven by power transmitting connections ill from the power shaft 20. The power shaft 20 has bearings as at 2| in the gear housing 22 and is coupled as at 23 with the main power shaft 24 having bearing as at 25 in the gear housing 26. See
Within the gear housing 26, the main power shaft 24 is coupled in driving relation as at 21 with two axially aligned cam shafts 28 and 29, the cam shaft 28 forming a part of the attachment herein disclosed and the shaft 29 being a part of the standard body maker or the main body forming section of the composite machine herein referred to. The axially aligned shafts 28 and 29 rotate in suitable bearings 30 supported on the machine framing. See Figure 1.
The machine attachment includes a blank grain breaking station generally designated 31 at which each blank fed from the stack is fed laterally
