WEB CUTTING, PRINTING, AND FOLDING PRESS.

SPECIFICATION forming part of Letters Patent No. 763,337, dated June 21,1904.

Application filed August 11,1902. Serial No. 119,173. (No model.)

' In the manufacture of cloth bag it is nec-' 1o essary that at various times pre etermined lengths of cloth be cut from a web, that these lengths be in many 'cases'printed with a desired pattern, and that said lengths be doubled accurately preliminary to sewing. It has 1 heretofore been customary in many'cases to cut the cloth Into the desired lengths preliminary to being carried to the printing-press and after they have been printed to pass them through a suitable foldingmachine or to fold 2o them by hand. In some cases it has also been customary to pass a continuous web of cloth through aprinting-press and thereafter to cut the printed web into desired lengths; but, so far as I am aware, difficulty has been experienced in the last method-in producing por-- tionsof uniform lengths. It is also necessary in any practical mechanism of this kind to provide means by which the length of the portrons may be very accurately determined and justment and by exceedingly small differences, for the reason that a difference of even so little as an eighth of an inch'would result in a considerable waste where the output is several thousand cuttings per day. The same is true of any material, such as paper or the like, predetermined portions of which are to be printed or folded.

The object of my invention is therefore to provide a mechanism in a single machine by means of which the forward or free end of a Web of cloth, paper, or other material may be grasped, a cutter caused to sever the web at a point between the end thereof and the web-roll at an accurately predetermined and adjustable distance from the free end of the web, and the severed portion of the web carried past suitable printing mechanism and carried through suitable folding mechanism whereby 5 it may accurately doubled upon itself and regulated within a considerable range of ad- 3 thereafter discharged from the machine, the feeding of the web, the printing, and the fold ing being accomplished automatically inproper sequence.

The accompanying drawings illustrate m invention.

Figure 1 is a side elevation of my machine, portions being shown in vertical section, the parts being in that position where one section of material has just been severed from the web and the preceding section of material is being folded. Fig. 2 is a similar view with the parts'in position where one section of the material is just being severed from the web.

Fig. 3 is a detail, on a larger scale, of the feed 5 rolls and. tapes and the cutting mechanism. Fig. 4- is an elevation of a modification, omitting the printing mechanism.

Inthedrawings, 10 indicates'the rotary impression-cylinder of a common form of multicolor-printing press, said cylinder being provided with gripper-fingers 11, operated in the usual manner by means of 'a cam 12, which comes into engagement with a stationary pin (not shown) in the usual manner, a spring (not 7 5 shown) being used, as usual, to normally hold said fingers in either position. Cooperating with the cylinder 10 may be a rotary typecylinder 13 and a reciprocating type-bed 1 1. Arranged above cylinder 10 and adjustable toward and from said cylinder upon ways 15 is a feed-roll and cuttercarriage 16. Arranged in carriage 16 is a transverse knife 17, and journaled in suitable bearings on the car-- riage is a rotary cutter-shaft 18, provided 5 with a shear-blade 19, which is slightly spiral, as is clearly shown in Fig. 3, and so arranged as to cooperate with the cutter 17 in a wellknown manner. Shaft 18 carries a cam 20, which cooperates with a pin 21, carried by a clamp-arm 22, pivoted at .23' to the carriage and provided with a clamp-finger 24, which at a proper time is brought down upon the cutter 17 immediately back of its cutting edge, so as to hold the web of material during the time of cutting. Leading to the cutter 17 from a point above the same are guides 25, which emanate from a point below the mouth of'a pair of feed-

rollers

26 and 27, feed-roll 27 beingpositively driven in the direction indicated 1 00 iii by the arrow by means of a chain or other of material 30, which proceeds from a suitable roll or other source of supply, passes around roller 29, between said roller and the roller 27, and between the roller 27 and the roller 26, falling from thence by its own gravity down the guides 25, past the knife 17, between said knife and clamp 24, and dropping from thence upon the upper sides of endless feed-tapes 31, which are supported upon

suitable rollers

32 and 33 above the impression-cylinder 10, guides 34 extending from roller 33 to the impression-cylinder. The

rollers

32 and 33 may be positively driven by means of a chain belt 35, which meshes with a sprocket-wheel 35, positively driven by a chain 36 by a suitable counter-shaft 37, which counter-shaft also drives the chain 28. Counter-shaft 37' may be driven from any suitable source of powersuch, for instance, as one of the shafts of the press. Cone-pulleys or the speed-changing gearing described in my Patent No. 655,133, issued July 31, 1900, would be interposed in order that the speed of the feed-rolls and feed tapes may be independently varied with rela' tion to the speed of the impression-cylinder 10. Geared 01' otherwise connected to the impression-cylinder 10, so as to have the same peripheral speed, is the first folding-cylinder 38, to which in turn is connected the second folding-cylinder 39. ripheral contact with cylinder 10-and is provided' with gripper-fingers 40 of an ordinary form and so arranged that when the gripperfingcrs'll of the cylinder 10 bring the end of the section of material adjacent the cylinder 38 fingers 40 will be in position to engage said section at the time the fingers 11 release the same, the fingers 11 being withdrawn from the cloth by the action of a suitable pin in the usual manner and the grippers 40 gripping the material in the usual well-known manner. Mounted within cylinder 38 and pivoted upon the shaft thereof is a bracket 43, which is adjustable angularly within the cylinder toward and from the gripper-fingers 40. Formed in bracket 43 is a radial slot 44, within which is mounted a folding-plate 45, which may be projected beyond the periphery of cylinder 38 by means of an arm 46, pivoted upon the bracket and swung by means of a lever 47 which is brought into contact with a stationary stop 48. (Shown in dotted lines in Fig. 1.) Cylinder 39 is provided with a peripheral slot, upon one edge of which is arranged a yielding gripper-face 49. Coacting with the gripper-face 49 are gripper-fingers 50, which are normally urged toward the face 49 by means of a spring 51. Connected to the gripper-fingcrs 50 is an operating-arm 52, the end of which engages a stationary cam 53, the arrangement being such that as the cylin der 39 rotates cam 53 will operate to with- Cylinder 38 is in petion thereof.

tapes.

draw fingers 50 from the gripping-face 49 and then allow said fingers to coact with said gripping-face immediately after the cloth has been forced into engagement with the gripping-face by means of the folding-plate 45. The cutter 19 is driven in any suitable mannersuch, for instance, as chain 54-in such manner that itis given onecoinplete rotation for each rotation of the impression-cylinder 10, the cutter 19 being brought into cutting engagementwith the cutter 17, so as to finish its out at the moment when grippers 11 engage the forward end of the web.

in operation the carriage 16 is so adjusted upon its ways that the distance between the gripping position of gripper-fingers 11 and the edge of the cutter 17 along a line which would be naturally assumed by the web be tween these two points will be equal to the length of material required, and the speed of shaft 37 is so regulated with relation to the speed of the shaft of cylinder 1Q that the speed of the feed-

rollers

26, 27, and 29 and the feed-tapes 31 will operate to bring the free end of the web into position tobe gripped by the gripperdingers 11 at'the instant when said gripper-fingers are'in gripping position and at the instant the knives come into action. Bracket 43 is then adjusted within cylinder 38 so that the folding-plate 45 will lie a distance from the gripper-fingers 40 equal to the distance between the forward edge of the severed portions of the web and the desired line of fold. With the parts so adjusted and moving in the directions indicated by the arrows the web after passing through the feedrolls drops down guides 25. between knife 17 and clamp 24, past the knife, and upon the feed-tapes 31, by which it is moved forward until its forward edge goes into the position shown in Fig. 2, at which time the grippingfingers 11 of the cylinder 10 will have been brought into position and operated so as to grip the web. Just at this moment cam 20 20 allows the clamp 24 to drop into engagement with the web and clamp it upon the knife 17.. The movement of the cylinder 10 places a slight tension upon the web between the gripper-fingers 11 and the cutter 17 and immediately the cutter 19 is brought into engagement with the web, so as to sever the forward por- The rotation of the feed-rolls being continuous, the oncoming web banks up behindthe clamp 24, and as soon as the cutter 19 passes beyond knife 17 clamp 24 is withdrawn, thus allowing the accumulated portion of the web to fall by its own weight down past the knife 17' and upon the feed- In the meantime the rotation of the impression-cylinder 10 has caused the severed portion of the cloth to be drawn past the printing-cylinders 13 and the reciprocating printing-platform 14 and around into engagement with cylinder 38, at which time grippers 40 thereof are in position to engage the forward end or me material, so that it is transferred from the impression-cylinder to the cylinder 38, the material wrapping around cylinder 38 with its point of fold lying over the folding-plate e5. rotated to a point where the folding-plate 45 lies in conjunction with the gripping-surface 49 of cylinder 40, plate 45 is projected by the action of arm 47and pin 48, so as to carry a bight of the material between the gripping surface 49 and the fingers 50, whereupon cam 53 allows the fingers 50- to grip the doubled portion or bight upon the. gripping-surface 4:9, whereupon folding-plate 45'is' immediately withdrawn, the portion of material being thus folded and transferred to the cylin-' der 39.. WVhen cylinder 39 has rotated so as to bring cylinders 50 at about the point X, Fig. 2 fingers. 50 are withdrawn from the gripping-snrface49 and the doubled material falls by its own gravity upon a suitable plat.-
