Title: Improvements in machines for coating web materials
IPC: D06B3/10
Filed: 1927-11-30
Abstract: 303,255. Johnson, J. Y., (John Waldron Corporation). Nov. 30, 1927. Coating materials in long lengths.-Web material to be coated is supported in its passage under a series of brushes, which distribute the coating material, by an arcuate shaped table which is adjustable vertically relatively to the web. Web material x<1> to be coated is fed from a roll x over and under guide rollers 2, 3, 4, 6, carried by the side frames 1 of the machine, to a chilled iron roller 7, after leaving which it passes over a rubber apron 15 stretched between hollow rolls 12, 16, one of which is higher than the other. The rubber apron with the web x' passes over an arcuate shaped table 20 faced with slate or other hard wearing material 73. The coating material is contained in a trough 27 and is fed by a partially submerged roller 28 to a rotary brush 26 which transfers it to the web x<1> near the roll 7. The material is initially spread by a stationary brush 29 and is uniformly distributed by a series of batteries of brushes 30, 31, 32 reciprocated horizontally by eccentrics acting on the brush carriers. After leaving the last of the brushes, the web x<1> passes over a perforated belt 21 carried by rollers 23, 24 and between which is situated a suction box 25. The batteries of brushes are adjustable relatively to the table, which is also adjustable vertically, to facilitate threading the web x<1>, and are rotated through belt and pulley gearing from a main shaft 91. A second shaft 101 drives, by chain and sprocket gearing, the roller 16 for the apron 15, the roller 23 for the belt 21, and the rollers 7, 12 and 28. The brush 26 is adjustable relatively to the reservoir 27 and roller 28, which are both adjustable on the machine framing. Tension is put on the web x' by applying a braking action, by a band-brake 130, to a drum 129 on the shaft 125 of the roll x which is supported in bearings 126 carried by beams 127 mounted to slide freely on ball bearings 128 supported by the machine frame. An adjustable weight 141 tends to turn a smooth roll 138 about its axis by a strap 139 passing over a pulley 140, to turn a pinion 137 on its shaft and in gear with a rack 135 on one of the beams 127, to move the roll bodily to the left of the Figure, when a wedge shaped arm 133 of a bell crank lever secured to the free end of the brake band is pushed under a fixed roller 134 to brake the roll x.

DE ENZO SERAGNOLI E ARIOSTO SERAGNOLI]. 18 July, 1967 [28 July, 1966], No. 32861/67. Headings B8A, B8C, B8D and B8S. Apparatus for emptying cigarette trays into a hopper supplying a packaging machine includes a head rotatable about a horizontal axis and capable of supporting two or more trays symmetrically relative to the axis, the head receiving filled trays and rotating to invert them over the hopper. While one tray is discharging, another is in a position to be removed and replaced. Infeed and outfeed conveyers.-Filled containers are fed in by conveyer chains 62, 63 and the empties discharged by chains 64, 65. The conveyers are arranged to permit trays to be slid on to them and discharged at right angles to their direction of travel. The chains carry two forms of support bar, Fig. 10, one, 191, having rollers 194 which engage the base of a tray and the other 190, of which there are several for each tray supported, having rollers 193 engaging the rear wall 105b, Fig. 11. Dogs 217, 218, Fig. 1, on reciprocating overhead conveyer chains 204, 205 slide the trays off and on to the inlet and discharge conveyers. Emptying containers.-The rotary head 98 carries two trays, each with their open faces against central webs 101 and their bases initially supported by a stepped portion 103. Catches (158, 159, 158<SP>1</SP>, 159<SP>1</SP>), Fig. 3 (not shown), protrude through the end plates 99, 99<SP>1</SP> of the head to hold them against the webs and pivoted bars (112, 112<SP>1</SP>, 113, 113<SP>1</SP>), Fig. 3, engage along the length of the open top. In their inner position, these bars overlap the ends of the uppermost layer of cigarettes, retaining them in place during rotation. A filled tray is fed by the overhead conveyer into position in front of the head and is pushed on to the portion 103 and against the web 101 by a reciprocating member 179. The member 179 includes an electromagnet 232 for engaging the tray which is of magnetic material. The tray is secured in the head by the catches. The head then rotates and the bars withdraw, permitting the cigarettes to fall into the hopper 233. While this is taking place, an empty container is fed to the discharge conveyer and replaced by a filled one. The apparatus is controlled by photo-electric means monitoring the cigarettes in the hopper. A pusher 229 discharges empties from the chains 64, 65.
