Title: Method and apparatus for packing
IPC: B65B19/28
Filed: 1974-12-13
Abstract: 1484486 Wrapping apparatus HAUNI-WERKE KORBER & CO KG 13 Dec 1974 [17 Dec 1973] 54097/74 Heading B8C Apparatus for packaging articles, for example blocks of cigarettes, comprises devices 3 and 4 for feeding articles and wrappers to a wrapping conveyer 9, the device 4 being rendered inoperative when a sensor 64 monitors the absence of an article, a device 56 for transferring the articles and wrappers to a second wrapping conveyer 22, and a monitoring device 67a, 67b which, on detection of the absence of a wrapper, prevents the transfer of an article to the second conveyer and returns it to the device 4 for the supply of a wrapper and also prevents the supply of another article by the device 3. An unwrapped article may be returned to the device 4 by the conveyer 9 which may comprise a turret or a conveyer chain with hollow mandrels 11, or by a separate conveyer. The article feed device 3 may be located at any point along the conveyer 9, but preferably before the device 4. In the latter alternative the sensor 64 is a photo-electric arrangement which detects the absence of an article within the mandrel. A second wrapper is fed by a device 6 unless reflection light sensor 66 detects the absence of a first wrapper which is of tin foil. The device 67a comprises a conductive sensor (98) to ascertain the absence of the outer wrapper, which is non- conductive, over the conductive tin foil wrapper and the conductive mandrel 11, and a photoelectric sensor to detect the absence of an article. There are two devices 67a, 67b each controlling a respective cigarette block forming device which supplies alternate holders in a supply belt 29. A photo-electric sensor 68 prevents the supply of a tab to a tab supplying turret 7 in the absence of a completed package to be transferred thereto from the conveyer 22. A scanner 36 controls an ejector 37 which removes incomplete or damaged cigarette blocks from the supply belt 29. The tin foil feeding apparatus 4 includes oscillating tongs 44 and a cutter 46. The outer wrapper feeding apparatus comprises a magazine 47 with a sensor 71, a reciprocable suction withdrawal roll 48 with a suction detector 74, a gumming device 51, and tongs 54. Folding stations 12-14, 16-19, 21, 24 and 26 are provided. The conveyer 22 has an uneven number of holders 23 and advances each step by two holders so that an article and wrapper complete one and a half revolutions before transfer to the turret 7.

Abstract: 1,260,550. Fluffy yarn. TORAY INDUSTRIES Inc. 24 Nov., 1969 [26 Nov., 1968; 5 July, 1969; 30 Sept., 1969], No. 57331/69. Headings D1F and D1W. In a method of manufacturing a fluffy yarn, a multifilamentary yarn is advanced towards at least one fluff-raising member, is caused to contact the fluff-raising members in a ballooning condition intermittently and partially, and the ballooning condition is maintained substantially constant throughout the operation. In apparatus for carrying out the process, one or more fluff-raising members 4 are located between an upstream guide 3 and a point whereat the yarn is wound on a take-up bobbin 1 so as to make contact with a ballooning portion of the yarn, each fluff-raising member 4 being pivotal about its axis and being provided on its peripheral surface with a cutting element for cutting the filaments, the distance between the yarn guide 3 and the point of yarn winding on the take-up bobbin being maintained constant. The fluff-raising member 4 may be positively rotated or rotated by contact with the ballooning yarn. The fluffraising member is preferably in the form of an abrasive surfaced bar which is set at an angle of less than 90‹ to the central axis of the yarn balloon. In an alternative embodiment, the fluff-raising member 4 is rotated by means of an air jet directed against wings provided on the member. In a further embodiment, the fluff-raising member is in the form of a disc positioned to contact the yarn balloon as the yarn is wound on to a package by a ring twister, the disc axis being parallel to the package axis. The disc is preferably rotated by means of an air jet. In a still further embodiment, the ballooning condition of the yarn is maintained by a false-twist spindle, the yarn passing to the spindle eccentrically, and the fluff-raising member contacting the balloon produced. In this case, the fluff-raising member may be a roller, or a series of rollers of different diameters. The cutting element of the fluff-raising member may alternatively be provided by a knife edge, or a screw-thread like surface. The fluff-raising member may incorporate flow conduits ejecting fluid whereby foreign matter sticking to the yarn contacting the surface of the fluff-raising member may be removed.

The yarn may not possess crimp or crimp may be present throughout the yarn or in sections or one or more constituent strands thereof. The yarn is formed by falsetwisting and heating at elevated temperature as selected (or calculated by use of a stated formula) in relation to the density and the degree of the double refraction characteristic of filaments comprising the strand(s). The latter may be pretwisted in the same direction as, but to a twist number of one half or less of, the subsequent false-twist. The filaments may be of synthetic thermoplastic material such as drawn or undrawn polyester or cellulose triacetate and of various cross-sectional forms.
