FIG.4
DEVICE FOR THE MANUFACTURE OF PAPER CUPS The invention concerns a device for the manufacture of cups made of paper or similar material and consisting of a conic mantle and a bottom portion or part, which is inserted in this mantle withits edges pointing toward the narrower-end of the mantle. As thus inserted the outer surface of these edges rests against the inner surface of the wall of the mantle.
Since the bottom surface of the bottom part is situated at a certain distance from the mantle, it must have an exterior diameter greater than the interior diameter of the narrower end of the mantle if its edge is to rest against the inner surface of the mantle. ln connecting the two parts, the bottom part has, therefore, so far been introduced from the wider end of the mantle. With a first, already known device, the cut mantle is rolled around a pin, which must be at least as long as the mantle if it is to form an abutment for bracing the entire mantle vseam against a pressing cheek.
Along this seam, the mantle overlap, which is provided with a layer of glue or a thermoplastic sealing film, is sealed or glued together by the use of a pressing cheek, applying heat if necessary, until the connection is tight. Thereafter, the mantle removed to another pin on whose front the cup bottom has been placed previously. This new pin is shorter at its'narrower end than.
the first pin in order to allow space for the bottom in the mantle.
The above described device provides on the one hand, the advantage of an even seal of the mantle seam along its entire length, but, on the other hand, it has the inconvenience of requiring the use of two series of supporter pins for the mantle, which, in turn, require normally two revolving tables for each series of pins.
A second known device avoids the double pin series by rolling and sealing the mantle on a pin after having placed the cup bottomon the front or in a recess of the front of the pin. In this case, the pin must be shorter than the cup, as the part of the case which is to receive the cup bottom, must be free of the pin. Therefore, the pin acts as abutment against the pressing cheek for only part of the total length of the mantle seam. Therefore for the time being, the seam can be sealed only from the open cup border to near the bottom. The remaining part of the mantle seam near the bottom will be glued or sealed, once the bottom is joined to the mantle. When the bottom edges are pressed on to the mantle, the still open part of the mantle is sealed simultaneously. Since this is carried out in two different work positions and since there are varying numbers of paper layers in the two areas to be sealed there frequently are badly sealed or unsealed parts of the joint near the bottom surface of the bottom part, i.e. in the front of the pin.
The object of the invention is, therefore, to provide a device of the above-mentioned kind, that avoids the necessity of two pin series as well as insuring a complete and total sealing of the mantle seam. The solution according to the invention consists in a device with the following characteristics:
a. The device has an arrangement for the sealing of the seam of the mantle part comprising a conic pin to hold the mantle part, a pressing cheek which presses the mantle seam from outside against the. pin and a movable abutment in the pin on the other side of the 1 of operation. The front part 3 of the pin mantle seam having a surface parallel to the surface of the pin. Both the pressing cheek and the abutment cover the total length of the mantle seam.
b. The device includes an arrangement for the insertion of the bottom in the mantle, including a conic pin to hold the mantle, which on its narrower end, according to the height of the bottom, shorter than the mantle,
tle.
c. The same pin which is used to-hold the mantle, is also used in the device to seal the seam and to insert the bottom. I
d. The abutment comprises a movable part which, in the seam sealing device acts to extend the pin surface at the narrower end of the pin and which can be removed when the bottom is inserted and/or worked on.
Since the abutmentin the device for the sealing of the mantle seam extends over the entire length of the seam, the seam can be sealed completely, even near the bottom surface. On the other hand, the pin leaves along its mantle line. During the operation of mantle formation it is pushed beyond the narrow end of the pin so as to have the total length of the seam supported by the strip. Subsequently prior to the insertion of the bottom, the strip is drawn back to have its front edge coincide exactly with that of the pin. I
' Another advantageous possibility is to mount a movable part of the abutment on the front of the pin from its free side, the front side of the pin and the nearer side of the movable part being fitted with interacting grooves which insure the required support of the movable part. I
The invention is described in detail below, with refer ence to the drawings: U
FIG. 1 shows a longitudinal section through a pin with a movable strip serving as an abutment;
FIG. 2 is a top plan view of the pin, according to FIG. I;
FIG. 3 shows a longitudinal section through a pin with a movable abutment part that can be mounted from the outside;
FIG. 4 shows the end of a pin with mounted mantle and an inserted bottom portion and FIG. 5 shows a partial section through a bottom edge of the pin and adjoining parts during widening of the bottom portion in the mantle. FIG. 1 represents a pin 1 of conic form, fixed on, e.g. a revolving table-above a shaft which is centrically designed on its thicker end. The machine has a number] of such pins which progress through the various points is flat and perpendicular to its medial axis.
Along a line of the'mantle, there is a groove 4 in the outer surface of the pin into which a strip 5 is fitted. This strip can move along the length of the groove and the outer surface of the strip conforms to the conic form of the pin. The strip must be able to slide at least I and a part for the insertion of the bottom into the manbetween a first terminal position in which its front surface 6, parallel tofront surface 3, coincides with front surface 3 (dashed line in FIG. 1) and a second terminal position in which front surface 6 extends beyond front surface 3 of the pin to allow sealing of the mantle seam along the desired length. To guide the strip, it is fitted with a roller which acts with appropriate guidance devices, such as guide-rollers, which have not been included in the drawing. The guidance device is synchronized to arrange for the strip to be pushed beyond front surface 3 during the phase of the operation when the mantle seam is sealed and to remain in the pin when the bottom is fixed to the mantle. The mantle to be formed and sealed on pin 1 is indicated as 7 in FIG. 1. Above strip 5, the mantle seam 8 can be recognized by the double layer of material. The strip represents the abutment for pressing cheek l l.
Another abutment is shown in FIG. 3. Those parts that have already been explained in FIG. 1 have the same numbers. Pressing cheek 11 is shown above mantle seam 8. On the other side, the seam is supported partly by pin 1 itself, partly by a supporting part 12. This supporting part consists of a guiding shaft 13 which can be moved axially on a guiding pivot not shown, and of a shoe 15 provided with a centering extension 16 which sits in a centered recess 17 arranged in the middle of the front part of pin 1. Both centering extension 16 and centering recess-l7 are conic. Moreover, the shoe 15 has an arched side part 18, which during the phaseshown when the shoe sits on front part 3 of the pin 1, corresponds to the conic form of the pin and rests against the inner surface of seam 8 to back it against cheek ll. Guiding parts 13 and 14 are inclined compared to the longitudinal axis of pin 1 to allow the unimpeded movement of the shoe l5 throughthe protruding edge 19 of the mantle into this edge. After seam 8 has been sealed in its entire length through this pressing operation, support part 12 can then be removed. The pin 1 supporting the sealed mantle progresses, after sealing of theseam, to another point in the machine, where bottom 20, comprising bottom surface 21 and edges 22, is introduced by part a (FIG. 4). The
present example supposes that the bottom portion, having been preformed with a diameter smaller than the end of the mantle, is introduced through the narrow open end 23 of the mantle. As indicated above, the bottom could also be brought into the desired position within the mantle by other means, for instance by pushing it into an empty space that reaches from the front side of the short pin toward its thicker end, before sealing the mantle, as explained in U. S. Pat. No. 3,157,339. In such a case, the movable strip 6 cannot be used, but
' the device according to the invention, with support 17 can be used.
After insertion of the bottom, the mantle edge is flanged in a manner seen in FIG. 5, using a flanger 24 parallel to pin 1 and moving axially to the latter. This A surface of mantle 7 as demonstrated by the full line in FIG. 5. Afterwards, the' edges may be sealed to the mantle.
