11 Claims.. (Cl. 164-22) This` invention relates generally to methods and devices for cutting articles from a web or strip of any material, by use of automatic machinery.
One object oi my invention is to provide a maand severing articles from a web of any material;
Another object of. my invention is to provide an improved method for making` articles from a showing the progressive steps for converting the web into finished articles of any material.
Fig. 4 is an end view of the strip or web. Fig. 5 is a plan view, of two sets of four each,
. of articles as they 'are severed from the web.
Fig.'6 is aneiid view of Fig. 5. Fig. 7 isa plan view, drawn to a large s oi" one set of four articles.
the supply roll A, and in the web. The punching operation follows to cut a circular opening D in the center] of each star cut. The advancing web is-then cut 'and chine for progressively die-cutting, punching,
` intermittently from the said roll A by the action' severed to provide a succession of units of paperboard' collars as shown by Fig. 5.
Referring to Figs. 1 and 2 of the drawings, the di'erent parts or members of the machine are ymounted on a suitable base I. i
Mounted in bearings 2 at one 'end of base I is a roll of paper A from which is drawn the paperboard web B. 'I'he web B is drawn uniformly and i of feed rollers I .Iournalled in brackets l secured ale,
Fig. 8 isa section through the cutting and severing'knives at 8-8 o'f Fig. 2.
Fig. 9 is a section through the star" "cutting dies at 9-9 of Fig. 2.
Fig. -10 is a partial view of the punching device at III-I0 ofFig. 2. I
Fig. 11 is a planview of the die base shown in Figs. 1 and 2.
Fig. 12 is an elevation view of Fig. 1l
Fig. 13 is a section "at I3-I3 of Fig. ll.
'Fig 14 is a partial section at Il-Il of Fig. l.
Similar reference characters indicate similar parts or features in all of the views.
It will aid toward an understanding of the machine and of the method of making paperboard collars, to first describe the product made bythe machine and the operation o! the machine. Fig. 5 illustrates' two units of four each of paperboard collars asthey are delivered from the machine. Fig. '7 illustrates at a larger scale one to base I. `It will be understood that the feed rollers 3 are in practice driven as required and at the proper-speed to intermittently draw the web of paperhoardfrom the roll A and advance it to the cutting and punching devices. 20
From the feed rollers 3 the paper web is first advanced to the "star cutting unit which comprises a die platen 5 secured to base I. Mounted above the die platen 5 is a die head 6' having' secured thereto a number of sets of cutting knives i 'I (Figs. 2 and 9). The knivesof 'each set extend radially outward from a predetermined point, to make star" cuts when pressed against the web of paperboard. The diehead 6 is operative'ly vpositioned. over the dieplaten 5, and reclprocally operated in timed relation with the the web as' shown-in Fig. 3. v
From the star cutting unit the web B is adadvancing web tomake fstar `shaped cuts C in vanced' to a punching device which punches round' holes D out of the web at the center of each fstar C previously cut in the web. -The punching unit comprises a punchplaten 8 (Figs. 1, 2, 10,111, 12, 13 and 14) secured toba'se I in advance of the star cutting unit. Thepunch plaisent is provided with a plurality of circular openings 9 eachof the size of the hcles desired to be made in the web B.- The edge portion, of the top surface III of the punch platen 8, around each opening 9 serves as a cutting edge. Mounted on and secured to the Itop surface of the .punchplaten 8.
`is a ball cage II (Figs. 2 and l0) which is prounit of four collars wherein C indicates .star
' cuts; D indicates circular lopenings and E represents division slots vwhich partially divide the unit to provide four individual collars. The division slots E do not .completely divide the unit in to separate collars, because a small connecting por` tion'F is left to. hold the four collars together for handling and packaging purposes. Before the collars are used they are separated by tearing at F to provide four individual collars.
In the operation of the' machine a web of paperboard B (Figs. 1 and 2) is first .drawn from vided with a plurality of openings I2 each of 'which guides and retains a spherical steel ball Il. The openings I2 are somewhat larger than the diameter o'f the steel balls Il.' Positioned above the ball vcage I I is a punch head Il reciprocally operated in timed relation with the advanciing webB, to strike the steel balls I3 positionedV on the said web. with the result that 4the steel balls press the web against the edges of the openings I2 on the top .surface I0 of the punch platen to punch out circular sections of the web B to provide openings D (Figs. 3. 5 and '1). Secured in which project below the bottom surface of the the star cutsa C made the punch head I 4 are adjusting screws Il punch head Il and serve as the contact element between the punch head and the steel balls I 3. The adjusting screws l5 serve to make uniform the striking force of the punch head against the steel balls.
When the punch head Il is in raised position the steel balls I3 rest on the web B. The web,
however, is free to advance, because the steel balls willroll on the web when the web is moved forward over the punch platen.
'I'his novel punching device is easily sharpenedby simply grinding the top surface I0 of the platen II to provide a new cutting surface around the` upper edge of holes 8'. The steel balls i3 being free to rotate present an infinite succession of punching surfaces. Thus the steel balls may be used for a long time without being resurfaced or replaced. i f y From the punching unit the web B is advanced to the slitting and severing unit which operates to divide and-sever the web into units of paper collars as shownin Figs. and '1. The slitting and A`severing unit comprises a-die bed i8 (Fig. 2) secured to base I. Positioned above the die bed Il is a die head I1 reciprocally operated Ain timed relation with the advancement ef the `web B.
' secured te the underside er the die head |1- are slitting knives I8 and severing knife I9 (Figs. 2
and') which, when4 the die head I I is moved downward, presses the web B against the platen IB and slits and severs the web to provide units of paper collars from the web.
It will. be obvious that with each downward e operation of the die head- I'I the severing knife It will be readily understood,- without needof Y, illustration, that any suitable motor may be employed for operating the machine; and that suitable gearing,v mountings and other mechanismsv are employed in practice to cause the variousA mechanisms to operate at the proper speed. 00 eii'ect travel of the web through the machine. and to cause theseveral units of the machine to operstein the sequence described.
