Patented Mar. 23, 1943 BEAD FORMING AND PRINTING DEVICE Yervant H. Kurkjian, Hawthorne, N. J., assigner to Julius Schmid, Inc., New York, N. Y., a corporation of New York Application April 27, 1939, Serial No. 270,427

8 Claims.

. .This invention relates to a means for rolling a bead upon tubular rubber goods or other articles, such as balloons, nger cots, and the like, and has for one of its Objects the production of a simple and efficient means for rolling a bead upon itself from the lower portion of the article through the medium of a lateral pressure frictional contact movable element to assure an economical and accurate operation in the rolling of the bead as well as the removal of the article from its supporting form after the bead has been rolled.

. A further object of this invention is the production of a simple and ecient means for facilitating the stamping or printing of the rubber goods prior to the rolling thereof upon the supporting form.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

In the drawings:

Figure 1 is a side elevational view of my device, certain parts being shown in section;

Figure 2 is a top plan View thereof certain parts being broken away;

Figure 3 is an irregular sectional view taken on line 3 3 of Figure 2;

Figure 4 is a fragmentary elevational View illustrating the cuter face of the printing mechanism and looking in the direction ofthe printing pad;

Figure 5 is a horizontal sectional view taken on line 5--5 of Figure 4;

Figure 6 is a vertical sectional view taken on line 6 6 of Figure 4.

By referring to the drawings, it will be seen that IIJ designates the supporting base which may be carried in any suitable or desired manner upon a bench or other supporting medium. A plurality of hangers I I are suspended from the bottom of the base I and support a` shaft I2 which is driven by means of a pulley I3 from any source of power. An operating pulley I4 is carried by the shaft I2 for actuating a vertically extending bead forming belt I5. This belt I also passes over an upper pulley I3 which is journaled between the vertically extending uprights I'I.

y2li placed intermediate the uprights I'I and near the lower ends thereof, as shown in Figure 3. In this way, the uprights I'I will be spaced for a greater `distance than the width of' the belt I5 in order to allow the belt to iiex inwardly between the uprights I1 if necessary.

The base I0 supports an annular track 2l which track is provided with a channel 22 in the upper face thereof. A form-supporting ring 23 is carried by the annular track 2l and is provided with aV depending annular ange 2G overhanging the inner edge of the annular track 2l, as shown in Figure 3 to hold the ring 23 against lateral displacement. This form-supporting ring 23' carries a plurality of vertically extending spindles 25 which may be mounted in any suitable or desired manner upon the ring 23 and carry ballbearing rings 25 at their upper and lower ends, as indicated in Figure 3. These rings 23 may be of the conventional ball-bearing type without departing from the spirit of the invention. Each spindle 25 is also provided with a vertically vextending central bore 2'I extending from end to end and communicating with the channel 22 in the annular track 2I. The annular track 2l is provided with apertures 23 at certain intervals communicating with apertures 29 formed in the base Il) to provide an air outlet opening in communication with the passage 21 of the' spindle 25.

A removable form 3@ is fitted over each spindle 25 and this form 33 is preferably of an elongated'tubular formation having a central bore 3| with which bore communicate a plurality of air ports 32 extending transversely through the form 3). This bore 3| communicates with the passage or bore 21 in the spindle 25 so as to allow air to escape through the ports 32 and out through the bore 3l through the passage 2l and apertures 28 and 29 as a tubular piece of rubber goods is slipped over'the form 36. Each forni 3e preferably tapers for a short distance near its lower end, as indicated by the numeral 33, so as to allow the lower end of the rubber articleV indicated in dotted lines by the numeral 34 to Contact around the lower tapering end 33, in this way facilitating the holding of the tubular rubber goods upon the form 30 where it may be engaged by the belt I5V as will be hereinafter described. This lower tapering end will provide means whereby the inner end of the tubular rubber goods may be restricted in size by tightlyr fitting around the tapering end to firmly hold the rubber gocdsupon the form and prevent the rubber goods from jumping off or becoming accidentally removed from the form. To facilitate the operation of the device, I provide a plurality of radiating finger-engaging pins 35 which radiate from the outer periphery of the form-supporting ring 23, as shown in the drawings, which pins may be engaged by the hand oan operator' for rotating the ring 23 in the direction of the arrows shown in Figure 2,y or these pins may be engaged and'in fact the ring 23`rna'y" b'e rotated in any' suitable or desired manner without departing from the spirit of the invention.

As shown in Figur-es 1 and 2, the ring 23 is positioned so as to cause the forms 30 to pass by in brushing contact with the face of the belt I adjacent thereto as the ring 23 is rotated in the direction of the arrows shown in Figure 2. The

belt I5, as shown, is supported by the pulleys I4 and I6, which pulleys are spaced respectively below and above the lower and upper ends of the forms 30, and the beltf-I5 is adapted to normally lie in close proximity to the face of one of the forms when one of the forms is brought into alignment therewith, in this way causing the endless belt I5 to frictionally engage the lower end of the tubular rubber goods 34 illustrated, when one form carrying the goods is brought into vertical alignment with the belt, in the manner shown in Figures l and 2. As the belt I5 passes in the direction of the arrows shown in Figure 1, this flexible endless belt I5 will Contact with the lower edge of the rubber goods 34 and will roll the same upwardly until the bead which is formed by this rolling action reaches the top of the form 30 whereupon the goods will be moved from the top of the form and thrown against the under face of the deflecting plate I9 and the goods will then fall into a receptacle or other container 36 placed in a proper position to receive the rolled goods. It is important to note that the belt I5 by being supported upon the pulleys I4 and I6 mounted beyond the ends of the forms 30 may slightly yield because of its flexible nature and at the same time keep a proper yieldable tension against the bead which is being formed, and cause the rubber goodsto be rolled upwardly to form the bead from its lower edge, in this Way avoiding the necessity of employing a brush or a direct and rigid bead contacting element.

It has been found by experience that the particular mechanism for rolling the bead is very important because of the engagement of the belt with the bead since this greatly speeds up the operation, provides for the formation of a uniform bead, and facilitates the removal of the article from the form after the bead has been rolled Without injury to the goods. Furthermore, the formation of the lower end of the form is important since this formation will facilitate the holding of the article in position and will Y prevent the same from jumping olf the form when the article is released from the hand of the operator.

I preferably employ four or more forms, such as are shown in Figure 2, and the device is placed in position where the operator will stand facing that portion of the machine marked Front, with the belt I5 facing to the left and the articles being removed toward the left of the operator. The ring 23 is moved in the direction of the arrows shown in Figure 2, and in a position to successively bring the forms into contact with the endless belt I5. The articles are placed upon the form which comes to the position directly in front of the operator and when each successive form comes to the position to register with the belt I5, the ring 23 is momentarily brought to a stop for a time sufficient to allow the goods to be rolled up upon the form and removed therefrom. In conjunction with this device, I employ a special printing mechanism indicated by the letter P, which will be hereinafter described and which mechanism in conjunction with the form constitutes a means for registering a one-fourth turn of the ring 23.

An air supply pipe 31 is supported upon the base I0 preferably in' the position directly in front of the operator and adjacent the far side of the inner face 38 of the ring 23, as shown in Figure 2, and this air supply pipe 31 is provided with an air discharge port 39 facing away from the operator and toward the form which is diametrically opposite the operator. This discharge port 39 is adapted to discharge a blast of air against" the face of the form which has just passed through the printing device P to facilitate the -drying of the ink. A valve 40 communicates with the air supply pipe 31 whereby the air supply may be turned on or cut off and this valve 40 may be connected to any desired source of air supply.

An inking pad 4I is carried by the upstanding arm 42 secured to the base I0 and is encircled by the ring 23. The pad 4I is preferably supported within a suitable frame 43 carried by the arm 42, the frame 43 being provided with an open face 44 so that the stamp 45 carried by the stamping arm 46 may engage the pad 4|. The pad 4I preferably comprises a fabric inkcarrying substance 41 wound upon a supporting plate 46 to facilitate handling and abutting against a rear backing plate 49. A pressure plate 50 engages the backing plate 49 and this pressure plate 5I! is engaged by an adjusting thumb-screw 5I extending through the upstanding arm 42, in this Way permitting the pressure of the pad to be adjusted when desired.

' The stamping arm 46 is journaled upon a vertical pivot 52 carried by the base I0 and mounted beyond the ring 23. A coil spring 53 engages the outer face of the stamping arm 46 and is carried by an upstanding post 54 supported upon the base I3. This spring 53 normally urges the stamping arm into contact with the inking pad 4I. The stamping arm 46 is provided with an inwardly extending cam flange 55 which is adapted to be engaged by the forms 39 as they successively pass between the stamping arm 46 and the pad 4I.

The flange 55 is of sucient width to cause the stamp 45 to engage the rubber goods carried by the form 3B as the form rotates across the face of the stamp in the direction of the arrow shown in Figure 2 and this can fiange 55 prevents the stamp from becoming compressed to too great an extent and limits the free swing of the stamp against the rubber goods 34. The coil spring 53 normally presses the arm 46 in a position whereby the flange 55 will engage the lower end of one of the forms as it passes to a position to spread the printing device P outwardly from the inking pad. As soon as the form has passed the printing device, the spring 53 will cause the stamp to again contact the inking pad, thereby reinking the face of the stamp. The outer end of the arm 46 is beveled, as indicated at 56, and as soon as the form has passed out of engagement with the arm 46 the operator will give the ring 23 a slightly backward push causing the side of the form to contact the beveled end 56 and thereby press the stamp 45 against the pad 4I. This operation may be easily accomplished and besides pressing the stamp against the pad for reinking, this movement will check the periodic engagement of the rubber goods with the bead-forming belt I5.

A blotting device B is supported upon the support I Il adjacent the end of the printing device P and comprises a horizontally extending frame 51 which is open, as at 58, and this frame'is preferably supported upon an upright 59 carried by the base I. Elastic bands 60 extend around the outer face ofthe horizontal frame 5l and span the opening 58. A clamp Bl is carried by the frame 51 and supports a blotter strip 62 which extends across the front faces of the bands B at the portions thereof which span the opening 58 and this blotter strip 62 is supported in a position to engage that portion of the rubber goods which has been stamped and the strip E2 extends in the direction of travel of the ring 23, as shown in Figure 2. This blotter strip will therefore facilitate the drying of the ink upon the rubber goods as the supporting form passes the blotter strip. In conj unction with the air blast, which is directed against the rubber goods at the portion thereof which has been impressed with the inked rubber stamp and the blotter strip, the stamped portion will be easily and thoroughly dried without the danger of smearing while the bead is being rolled.

It should be understood that the supporting ring 23 rotates about the annular track 2i and that the forms 23 are also freely rotatable upon the spindles 25. It should be further understood that the rubber articles are rolled upon the forms from their open ends toward their closed ends and toward the upper ends of the forms where the goods will be thrown off in a lateral direction from the forms and be deflected through the medium of the outward and downwardly curved deiiecting members i9.
