JOHANN CARL MLLER, OF DRESDEN, GERMANY.

APPARATUS FOR MAKING MOUTHPIECE-TUBES.

Specification of Letters Patent. Patented NOV. 29, 1910.

Application led November 15, 1909. Serial No. 528,142.

To all whom it may concern:

Be it known that I, JOHANN CARL MLLER, a citizen of the German Empire, residing at Dresden, in the Kingdom of Saxony and Empire of Germany, have invented a new and useful Improvement in Apparatus for Making Mouthpiece-Tubes, of which the following is a specification.

The objectofthe present invention is to perform the operations which havehitherto been performed by hand, by machinery. When makingl spiral mouth-pieces by hand in the usual Way, the blank for the mouthpiece formed of a sheet of paper or similar material, which is cut obliqu'ely at one end, is first rolled at the sharp angular end loetween the palm of the left hand and one finger of the right, whereupon the rolling process is completed by both palms to finish the mouth-piece. This operation requires considerable manual dexterity and training, and therefore requires the employment of skilled labor.

The apparatus embodying the present invention is so constructed as to carry out a similar operation with a blank formed as stated above, with the difference that the corner at which the rolling operation comlnences is caused to abut-against and to be deflected in a gage arranged in the path of its movement, said gage having a rounded groove or recess for deecting the corner. lVhen the corner has thus been curved or rolled, the gage is Withdrawn and the blank, continuing its movement, is rolled up between a forwardly moving surface and a stationary surface somewhat inclined with regard to the same in order to allow of the increase in. thickness of the rolled-up mouthpiece. Thereby the blank is rolled up 4into the desired form. This operation can be performed by various mechanism under my invention, an essential feature, however, being that the acute angled corner or forward end of the mouth-piece blank meets the detlecting gage in its path, and that said deflecting gage at the proper period is withdrawn and the mouth-piece then is carried forward by a moving surface and held at the same time in contact with a fixed surface opposite thereto.

In the accompanying drawing: Figure l represents a vertical longitudinal section of an apparatus embodying myinvention; Fig. 2 a-plan view thereof; Fig. 3 a detail in side means for operating similar View of still another modification;

and Fig. 6 a vertical sectional detail vievsT thereof.

Referring to Figs. 1 .to 3, it Willlbe observed that B is a feeding table for the blanks having guide-flanges a to guide the strip of paper A as it is fed into the machine. The said paper blank A is of .the form shown in Fig. 2, that is to say, it has parallel sides and 1s cut obliquely at its for- Ward end.A

In advance of the feed-table B is arranged the movable apron b which passes over Ithe end rollers o and d and is caused by the roller d to travel in the direction of the arrour in Figs. 1 and 2. The said apron runsv over and is separated by the bed 1I. Movement is imparted to the roller d and hence to the apron b in the direction of the arrow, by the driving shaft 71, upon which is keyed a gear-Wheel g which meshes With the gear f, which in turn meshes with the gear e, fixed upon't-he shaft of the roller d. An idler 7c is mounted above and heldin contact with 'the apron b, as shown' best in Fig. 1. This idler 7c, in connection With the apron b, serves to feed the blank A forward, as will be understood. 4

In advance of the roller or idler In is arranged the deflec'tng gage l, which, as shown, is provided at its face opposite theidler 1' With a curved concave deflecting surface, said concave surface facing toward the feeding end of the machine. Said deflccting gage, as shown in Fig. 2, extends only partially across and over the apron Z2, it being necessary only that it extend into the path 4of the forwardpointed end of the blank A.

As shown in Fig, 1,- the concave deflectingl surface of the gage is substantially tangential to the surface of the moving support. This molding gage is provided With means for projecting it into the path of the blank A and withdrawing it from the same, such movement being timed in such a Way that the gage will be .in the path of the blank about the time that the corner of the same reaches the part of the apron onto Which the gage is adapted to extend, and is held in such position until the-forward corner has been 4rol-led up suiiieiently, whereupon it is Withdrawn so as to permit of the continued forward motion of the blank. A

The mechanism for so actuating the dcflecting gage 7 is the following: The said gage is mounted upon a spindle n, said spindle being provided with a collar a. Abearing 7i is secured to a slide 0, and in this bearing the spindle n is adapted to slide transversely with respect to the apron 7). A helical spring -w euch-cles the spindle and is held between the collar ln. and the bearing 2) in such a w: as to yieldingly urge the spindle and. with it, the deflecting gage forward, so as to occupy the position shown in the draw ing over the apron 7). ln order to periodically withdraw the said spindle and the deflecting gage 7 from this operative position, into a position away from said apron, the slide o is arranged to be yieldingly urged in a longitudinal direction toward the feeding part of the machine by a spring w attached to a bracket ar mounted on a fixed portion of the machine and to the said slide 0 at o. On a. fiXed portion of the machine there is arranged an incline or cam surface n, (see Fig. 2), which incline bears against a lug t fixed to the spindle n and which is so arranged with respect to the same that when the slide 0 moves toward the delivery end of the machine, the incline u, bearing against the lug t, causes the spindle and, with it, the deflecting gage 7 to be withdrawn transversely out of the path of the blank A, as will be clear from an inspection of Figs. 2 and 3.

In order tol move the slide 0 in the direction of feed indicated by the arrow, and against. the stress of spring fr, so as to cause the incline or cam surface u to engage the lug f so as to withdraw the spindle n and the dellecting gage 7 away from the path of the blank A and against the stress of spring e, there is provided a cam disk r, Fig. :2. keyed to the shaft 71, said cam disk Ir being adapted to impinge against a friction roller s jonrnaled on standards rising from the slide o, as shown in Figs. 2 and 3.

Upon the shaft 71y is mounted a roller my which is covered on a portion of its periphery with a rubber mantle m which is adapted to come into contact with the forward corner of the blank as the same is being curled or started by the defiecting gage and which. therefore` serves in further curling or rolling said corner, the roller fm, as will be noted, turning in the direction of the arrow thereon, that is to say, in a direction opposite to that of the movement of the apron 7;. As stated, said roller is only partially covered with the rubber mantle, the other portion of its periphery being so arranged that it will be out. of frictional contact with the corner of the blank already rolled as the rubber mantle leaves the same. The roller m, it will be noted, is arranged over the moving support. and behind the defiecting gage, Z, that is between the latter and the feeding end of the machine.

To the rear of the roller m is arranged the counter-surface lw consisting of a fiXed plate slightly inclined with respect to the bed z' and the upper portion of the apron 7). There is thereby formed a wedge-shaped space betwcen which the blank A is carried forward bythe apron 7), the said blank being thereby rolled up, as shown in Fig. l, by the combined action of the moving surface of the apron I and the fixed surface of the counter surface ai, as will be readily understood. Said counter surface, as shown, extends to the rear of the machine and substantially to the end of the apron 7J.

The operation of the machine so described will be. clear from the foregoing.

A blank A is introduced into the machine on the feed table B, is taken into the bite of the apron 7) and the idler 7c and carried forward until its forward point strikes the deiiect-ing surface of the deflecting gage Z, which is at this time in the path of the said blank. The forward corner of the blank is then curled and turned by the combined action of the defiecting surface and the curling roller m. When the front pointed portion of the blank A has been sufficiently rolled up, the defiecting gage Z is withdrawn transversely out of the path of the blank by the action of the cam surface u, impinging against the lug t on the spindle n, the cam r bearing against the roll-er s and forcing the slide o in the direction of the arrow, Fig. 2, against the stress of the spring The blank then passes forward into the wedge-shaped space between the apron 7) and the counter-surface w in which space it is completely rolled up and discharged from the machine after having passed the lengt-h of the apron 71. The deflecting gage being mounted on the reciprocating slide 0 is caused to be moved forward to a slight extent in the direction of feed while being withdrawn and while the initial rolling operation is going on. Thereby the corner already rolled is more effectively introduced between the moving support and fixed counter-surface. The operations may be timed in such away that, after the rst rolling of 'the corner of a blank has been performed. a second blank is introduced into the machine, a third blank being completely rolled at the same time between the apron 7) and the counter-surface fw.

In Fig. 4 I have represented a somewhat modified form of the device under my invention. In this case means for feeding the paperstrip or blank consists of the feedrollers C and i) which here take the place of the feed-table B. The movable support is in this case in the shape of a drum E instead of an endless apron as in Fig. l. 'lhe defecting gage l and thc curling roller m are the same as in the first described construction. The counter-surfacc w. however, is in this case bent as shown, instead of straight as in Fig. 1. In this case again the pace between the movable support or drinn i and the counter-surface w .is wedgeshaped, that is to say, Haring forwardly toward the delivery end.

Still another 'modification under my invention is shown in Fig. 5, which differs from the first described form shown in Fig. 1 in that the deflecting'gage Z is arranged at the beginning of the endless apron I) instead of being mounted at an intermediate point of the same, as in Fig. 1. Under this construction the `paper strip, on undergoing its initial curling action, does not come into v any contactwhatever with the endless apron,

the feed of the same into the machine being performed in this case as in the construction shown in Fig. 4, by the initial feed-rollers C and D arranged in advancev of the table F to the delivery end of which the gage is attached, as shown. The first rolling or curling of the forward end of t-he blank is here performed by the deflecting gage which turns up the said edge or point until it strikes against the roller m the frictional portion of which, m', then coperates with the said deflecting gage to curl up the said edge or point to impart to saidblank the initial rolling up or curling. This arrangement will be in many cases sufficient to produce the necessary initial curling, butin general I prefer the arrangement under Figs. 1 and 4 whereby such initial curling is performed by the deflecting gage in cooperation with both the curling roller m and the movable support b or E, as the case may be. Under this modification. when the first rolling of the paper strip is finished and under the construction of Figs. 1 and 2, the

paper continues its movement by virtue ofl the rollers C and D and passes on to the endless apron or movable support b and between it and the counter-surface fw, where the further operation vis the same as under the first described construction. Under this construction it is ,preferable that the lowerl edge of the curved defiecting groove in the gage l does not lie above the edge of the table F, because, in that case, there would be a danger that the corner of the blank or paper strip would be bent in suc-h a way that it could not be curled readily. For this reason, as shown in Fig. 6, the lower edge of the said groove is a little below the edge of the table F, although it would be sufficient if it were just flush with the same. Under all the forms shown in the drawing, the length of the gage transversely of the movable support is such that after the same has completed the curling action of the forward the deflecting gage Z is moved away, as.

l end'of the paper blank the entire gage can be withdrawn from the apron in suflicient time to allow the initially curled blank to pass rforward between the movingbase and the counter-surface without interruption. In this way a continuous action of the machine is assured.

While the to the making of paper tubes and particularly mouthiece tubes, it is to be understood that t e same is a plicable also to makingtubes from other slheet material.

Reviewing the operations carried out-bv the above machine,'it will be noted that they consist essentially in first deecting the pointed tip of an obliquely cut blank and then curling the same spirally upon itself and thencarrying the blank bodily forward and at the same time causing the curled portion of the same to work over a fixed surface. This curling action may be carried out under my invention by the coperation of the deflecting gage having the curved groove presented toward the blank and arranged in the path of said blank, withy a curling' roller such as m which moves in a direction opposite to the direction of the feed of the said blank, said parts, under what I consider the best construction, coperating also with a movable bed such as a, movable apron as b, Fig. 1, or drum as E, Fig. 5. The curling roller m having a frictional surface m', al though in most cases suiicing to curl up the front edge o r point of the blank, is greatly aided by such movable support which carries the blank bodily forward. By having the roller m provided only partly with a frictional surface and partly with a nonfrictional surface, I attain the valuable result that as soon as the blank has been initially curled and the gage l has been withdrawn from the path of the paper, the said paper is positively lfed forward by the movable bed without interference from the roller m and without necessitating the lifting away of said roller as would be the case were the same covered entirely with a frictional surface.
