Description

Uppfinnare: A Johnek Uppfinningen avser ett satt att mata langden av en av porost material, exempelvis garu eller tyg, bestiende materialbana i r8relse genom att medelst en detektoranordning rakna markeringar astadkomna medelst en i beroende av detektoranordningen arbetande markeringsanordning. Inventor: A Johnek The invention relates to a method of feeding the length of a web of material consisting of porous material, for example garu or fabric, by moving straight markings by means of a detector device by means of a marking device operating in dependence on the detector device.

Vid ett kant sadant salt utgaras detektorerna av fotoceller och markeringarna av fargfldckar, som kvarsta efter matningen, nagot som ofta är en pataglig oldgenhet. At an edge of such salt, the detectors are made up of photocells and the markings of color spots, which remain after feeding, something that is often a pathetic antiquity.

Uppfinningen, som avser langdmatning av synnerhet garn och tyg, vid vilka material det ar onskvart att kunna utfora matningen utan att anbringa synliga, efter matningen kvarstaende markeringar, kannetecknas i huvu.dsak &ray, att man i materialbanan astadkommer markeringarna bildande, joniserande partier. The invention, which relates to longitudinal feeding of yarns and fabrics in particular, in which materials it is undesirable to be able to perform the feeding without applying visible markings remaining after feeding, can be characterized mainly in the formation of the markings forming ionizing portions.

Uppfinningen askadliggores schematiskt pa bifogade ritning, ph vilken 1 betecknar en rorlig materialbana, vars matningsriktning antages vara frau vanster till hoger enligt ritningen. Intill materialbanan 1 aro station art monterade dels en markeringsanordning bestaende av en lamplig stralningskalla 2, medelst vilken en tillfallig jonisering astadkommes i det for stralningen utsatta partiet av materialet, och dels en av de joniserande materialpartierna paverkbar detektor 3, som är anordnad pa det med L betecknade avstandet fran stralningskallan efter denim raknat i materialbanans matningsriktning. Stralningskallan 2 är inrattad att, shsona antydes pa ritningen me-deist den med 4 bet eck,nade pilen, astadkomma en jonisering av med jamna mellammm f8rdelade partier v materialbanan 1. Joniserings anordningen 2 är anordnad att paverkas for astadkommande av jonisering genom tillforande av en elektrisk impuls. Detektorn 3 ar i sin tur inrattad att for varje densamma passerande joniserat parti av materialbanan avge en elektrisk impuls, som via en ledning 5 tillfores joniseringsanordningen 2, sh att denna utfor en fly jonisering for varje gang ett joniserat parti passerar detektorn 3. De joniserande partierna komma hfirigenom att bli fordelade pa materialbanan pa avstandet L fran varandra. Till joniseringsanordningen 2 är vidare medelst en ledning 6 ansluten en elektrisk pulsraknare 7, som mottager och registrerar en impuls for vane av joniseringsanordningen 2 utford jonisering. Den foal matningsanordningen frammatade langden av materialbanan erhalles salunda genom multiplikation av den kinda strackan L med antalet av pulsraknaren 7 registrerade impulser. Pulsrb.knaren 7 är lampligen av den typ, som kan installas for avgivande av en impuls vid uppnaende av ett visst antal registrerade impulser. Harigenom kan man pa pulsraknaren 7 installa den langd av materialbanan, som skall behandlas, och utn.yttja den vid uppthendet av den installda langden avgivna impulsen for avbrytande av behandlingsprocessen. For startande av matningsanordningen forefinnas pa ritningen icke visade anordningar for tillforande till joniseringsanordningen 2 av en impuls, som utloser den forsta joniseringen av materialbanan 1. The invention is schematically illustrated in the accompanying drawing, which denotes a movable web of material, the direction of feeding of which is assumed to be from left to right according to the drawing. Adjacent to the material web 1 is station art mounted a marking device consisting of a suitable radiation source 2, by means of which a temporary ionization is effected in the portion of the material exposed to the radiation, and partly a detector 3 which can be actuated by the ionizing material portions, which is arranged on L denoted the distance from the radiation head after denim shaved in the material direction of the web of feed. The radiation source 2 is designed to, as indicated in the drawing by means of the arrow indicated by 4 arrows, effect an ionization of evenly distributed portions of the material web 1. The ionizing device 2 is arranged to be actuated to effect ionization by applying a electrical impulse. The detector 3 is in turn arranged to emit for each same passing ionized portion of the material web an electrical impulse, which is supplied via a line 5 to the ionizing device 2, so that it performs a fly ionization for each time an ionized portion passes the detector 3. The ionizing portions thereby becoming distributed on the web of material at a distance L from each other. An electrical pulse counter 7 is further connected to the ionization device 2 by means of a line 6, which receives and registers an impulse for the habit of the ionization device 2 challenge ionization. The length of the material web fed by the foal feeding device is thus obtained by multiplying the kinda distance L by the number of pulses registered by the pulse counter 7. The pulse generator 7 is suitably of the type which can be installed for emitting a pulse when a certain number of recorded pulses are obtained. In this way it is possible to set on the pulse calculator 7 the length of the material web to be treated and to utilize the impulse emitted when the set length is obtained for interrupting the treatment process. To start the feeding device, there are devices not shown in the drawing for supplying to the ionization device 2 a pulse which triggers the first ionization of the material web 1.

Uppfinningen fir icke begransad till den endast sasom exempel ovan beskrivna och ph. ritningen -visade utforingsformen, vilken kan forandras till sina detaljer, utan att uppfinningens grundtanke frangas. The invention is not limited to the example described above and ph. the drawing - showed the embodiment, which can be changed to its details, without departing from the basic idea of the invention.
