Definitions

  • This invention relates generally to expansible printing bands for stretched and interlocked mounting on annular seats on a rotary printing drum and more particularly to an elastomer e'xpansible printing band made integrally annular by attachment of its ends.
  • each printing band is stepped along -'both marginal edges to overlie these seat dividing flanges "onthe drum and to'engage'with the adjacent printing band 'to provide continuous lateralas well as annular printing.
  • the continuous as well as the attach- Iable printing bands may produce the same printing designs.
  • the problem here is to not only provide the fastener -to join the ends of the elastomer but to provide a continuous design after the ends are joined in a single band on thedrum. This is accomplished by requiring the elastomer-to be stretched to fasten its ends together and the design formedon the elastomer when made will mate at its ends and the stretch completes the design across the abutting ends.
  • the socket was devised with four sections, the first a mold supporting section or lip that is clamped in the mold to'hold the socket in place.
  • the second section is the bottom of the socket and has upwardly extending marginal flanges to close the sides of the socket.
  • the top section is next to the bottom section and the last or inturned end section carries the teeth that interlock with 3,230,878 Patented Jan. 25, 1966 "ice the teeth on the tongue and is folded in between the top and bottom sections and closed on the sides by the marginal flanges to prevent the elastomer upon molding from entering in the socket.
  • the flanges may be welded or soldered to the top section or the flanges may be made long enough to fold over the top section but not overlap each other.
  • the band between the bottom and top sections at the inner end of the socket should not have holes or the rubber will force its way into the socket.
  • FIG. 3 is an enlarged sectional view taken on the line '33 of FIG. 1 showing the drum seat with the printing band thereon and with parts broken away.
  • FIG. 4 is an enlarged sectional view taken longitudinally of the drum showing the lateral cooperation of adjacent bands.
  • FIG. 7 is an enlarged perspective view of a socket partially formed.
  • FIG. 8 is an enlarged perspective view of a folded socket.
  • FIG. 9 is an enlarged perspective view of a folded socket with its sides flanges secured as by welding.
  • FIG. 10 is a sectional view showing the tongue and socket held in the ends of a mold.
  • the expansible elastomer printing bands are indicated at 10 and their ends have been fastened together to form complete bands or rings and are mounted'on the printing drum 11.
  • This drum has a cylindrical portion 12 provided with the spaced annular grooves or seats 13 separated by the continuous radial flanges 14 and at-the drum ends by the flanges 15.
  • the cylinder 12 is hollow and has a stepped bore 16 at each end in which is secured a set of discs 17 and 18 for carrying the cylinder'on the stepped shaft 20 for the purpose of rotatably supporting the drum 11 in suitable bearings.
  • This drum is preferably driven so that the peripheral speed of the printing bands is in synchronism with the lineal speed of the strip or sheet in which it is in engagement to print the same.
  • the drum 11 is secured relative to the shaft 20 by means of the discs 17 and 18 as by welding as indicated at 21 in FIGS. 2 and 4.
  • the printing band 10 has a base section 22, the bottom of which engages the seat 13 and the top of which supports the upstanding indicia 23 which in FIGS. 1, 3 and 4 represents a hexagonal honeycomb.
  • the indicia 23 of each band On the lateral faces of the bands that portion 24 of the indicia 23 of each band makes up the complete mark.
  • each band may support half of a single printing line. In this manner the printing bands cooperate laterally with each other.
  • the base 22 of the printing band is provided with the lateral shoulders 25 which overlie and have complete support on the peripheral surface of the annular flanges 14 that define the seats 13 on the drum 11.
  • Substantially half of the thickness of the base of the elastomer printing bands engage each other as indicated at 25 in FIG. 4, thus providing lateral support from one band to another along the drum.
  • the flanges 25 on each side of each band are fully supported by the cylindrical surfaces of the radial flanges'14 on the drum, so every part of the printing band is supported or backed by the drum 11.
  • Each printing band is provided with a plurality of lugs or teeth 27 disposed transversely of the base and which interlock in the transverse grooves 28 cut across the bottom of the seats 13. These interengaging teeth prevent each printing band from slipping around the drum. In this manner the bands are held on the drum so that they may properly cooperate with each other in printing a continuous lateral and longitudinal design along a moving strip of steel, tin plate, cloth or paper.
  • the bands are made in fiat molds as shown in FIG.
  • the mold 30 has a bottom half 31 and a top 32 and is split along the line 33 with the cavity at 34.
  • This mold is preferably made as a multiple mold memher, only one portion of which is shown.
  • the other mold cavities are beyond that shown in FIG. 10 and the gates for changing and alternating the air, when required, may be in the center and ends, but are not shown.
  • the elastomer printing bands are formed flat and the split molds hold the metal tongue 35 that is a fiat strip with two or more openings 36 around which the clastomer is molded.
  • the other end of this tongue has a series of at least four upwardly and inwardly struck teeth 37 that are retained in the hollow portion 38 of the die or mold 39.
  • part of the tongue is clamped by the mold halves to retain it in proper position while the material is injected into the mold.
  • the mold halves clamp tightly on the intermediate portion of the tongue and on both sides of the teeth. These mold parts are relieved to receive the tongue and still tightly clamp on the same to prevent the elastomer from leaking out the mold and filling around the teeth 37.
  • the metal socket 40 is provided with a mold support section 41, a bottom section 42 of the socket with upturned marginal flanges 49 and a next and top section 43.
  • a And a last and inturned end section 44' which when folded along 45 against the top section 43 forms the in FIGS. 7' and 8 they may be folded over the top section 43, but they are not intended to meet, but only to hold the assembly and close the holes at the ends of the bends 45 and 46 to prevent the elastomer from entering the socket.
  • the mouth 50 of thesocket formed by the front ends of the flanges 49 and the told 45 are in one plane and when the mold support section 41 is inserted in the alleviated portion 51. The mouth 50 is seated tightly against the end wall of the die 30 so no' elastomer can enter the socket here.
  • the mold of 'FIG. lO'with the tongue 35 and socket 40 in place is ready to receive the elastomer.
  • the socket of FIG. 7 is completely folded.
  • the flanges 52 are made shorter than the flanges 49 and the edges of these flanges are either soldered or welded to the top 'section and top of the socket when the top is folded along 46. This at the bends and 46 as indicated to prevent any seepage of elastomer into the socket.
  • the mold support section 41 of the socket is cut off so as to present a smooth face on the end of the elastomer permitting it to match along the line 53 as seen in FIG. 5.
  • the tongue 35 is inserted in the mouth of the socket and the ends of the elastomer abutting each other will become slightly deformed so that the teeth 37 of the tongue 35 will pass the teeth 47 of the socket 40 and when released as illustrated in FIG. 5 will form a complete band which is with the elastomer engaging along the line 53.
  • the band may be removed from the drum by stretching .the same in a manner as though the band were made as one integral ring.
  • the fastening members forming this expansible' elastomer printing band make these bands more readily and quickly adaptable to the drum. If one were to break or become worn, making it desirable to renew the same, the band may be stretched, and removed ,from the drum or it may merely be stretched and .cut to be removed from the drum and a new band replaced, without losing much time which is an important factor of the improvement of this invention.
  • the printing bands are exposed to diiferent chemicals and it is desirable at times to select different types of metals for the tongue 35 and the socket member 40, and in order to avoid corrosion or eating of the metal it may be coated before being molded into the elastomer. 7
  • This simple fastening means forming a continuous band saves considerable expense and time in originally mounting and replacing expansible elastomer printing bands on the drum which saves a considerable, cost in the production in which the printer is employed.
