Abstract

1467700 Laminating method and apparatus ZIRISTOR AB 6 Aug 1975 [15 Aug 1974] 32893/75 Heading B5N A web of laminate material for packaging (Fig. 1) comprises a base layer 1 having bonded to one face a covering layer 3 of plastics material extending from edge to edge of the base layer, and, bonded to the other face, a covering layer 2 of plastics material which stops short of one edge of the base layer to leave an edge zone 11 of the base layer uncovered, and extends beyond the opposite edge of the base layer to provide an edge flap 4 of the covering material projecting therefrom. The base layer may consist of a foamed plastics or fibrous material, e.g. paper, and each layer of covering material may be a layer of plastics or of aluminium foil coated on each face with plastics, polyethylene being the exemplified plastics. The product may be used in the formation of a packaging tube, the joint, formed by sealing in the regions 5, 6 enclosing the base layer. The web may be made by coating the base layer in the form of a web with the plastics material, severing the web along longitudinal parallel lines to form a plurality of separate webs, side by side, applying a common coating layer of the covering material to the uncoated faces of the severed webs, severing the common covering material along lines parallel to, but laterally spaced from, the lines of severance between the separate webs, the edge zones of the web defined by the severance lines of the common covering layer being rendered substantially adhesion-free, before or during application of the common covering layer. An apparatus for effecting the method comprises means, e.g. an extruder, for coating one face of a web of base material with covering material incorporating plastics material, means for longitudinally severing the web into a plurality of side-by-side webs, means for applying a common layer of covering material to the uncoated faces of the severed webs, means for rendering a narrow edge zone of each of the severed webs free of adhesion to the covering layer and means for longitudinally severing the common covering layer along lines parallel to, but laterally spaced from the severance lines between the webs, where the common covering layer is non-adherent to the severed web. In the embodiment described with reference to Fig. 2, a web of laminated material consisting of the base layer 1 and the layer 3 of coating material is fed directly from a laminating device (not shown) to a first set of spaced cutting elements 8, e.g. rotary cutters, an adhesion-free zone 9 on each strip being formed by the application of an adhesion-inhibitor, e.g. wax or a silicone, to the base layer prior to the application to the strips of a common covering layer 2, e.g. by extrusion and nip-rolling. The resultant composite material is then passed to a second set of cutting elements 10, e.g. rotary cutters similarly spaced but laterally displaced from the cutting elements 8 which divide the upper layer of coating material into strips but do not act fully through the thickness of the composite material. In an alternative embodiment, the formation of the adhesion-free zones is effected using a lamination roller provided with peripheral grooves, the width and spacing of which correspond to the width and spacing of the zones.

Description

Изобретение относится к технике изготовления слоистых материалов и может быть использовано в пищевой, химической и других отраслях промышленности для применения в пакетах, 5 наполняемых различными жидкостями, преимущественно молоком.The invention relates to techniques for the manufacture of layered materials and can be used in food, chemical and other industries for use in bags 5 filled with various liquids, mainly milk.

Известен способ изготовления слоистого материала, состоящего из основного слоя и полимерного покрытия, Ю предусматривающий разрезание материала на параллельные полотна £1] .A known method of manufacturing a layered material consisting of a base layer and a polymer coating, providing for cutting the material into parallel webs £ 1].

По известному способу предусматривается, что один слой покрытия высту*пает за основной слой у одной кромки 15 слоистого полотна.According to the known method, it is provided that one coating layer extends beyond the main layer at one edge 15 of the laminate.

Поскольку слоистые полотна, изготавливаемые на листопрокатных машинах, в несколько раз шире, чем полотна, используемые в упаковочных маши- 20 нах, первоначальные полотна приходится разделять на несколько более узких полотен, ширина которых приспособлена к данным упаковочным машинам.Since the layered webs manufactured on sheet rolling machines are several times wider than the webs used in packaging machines, the original webs have to be divided into several narrower webs, the width of which is adapted to these packaging machines.

Таким образом,при изготовлении ма- 25 териала по известному способу увеличиваются технологические отходы.Thus, in the manufacture of material according to the known method, technological waste is increased.

Целью изобретения является снижение технологических отходов при изготовлении материала.The aim of the invention is to reduce technological waste in the manufacture of the material.

Это достигается тем, что в предлагаемом способе изготовления слоистого материала разрезание слоев материала проводят в два этапа, сначала разрезают на параллельные полотна ос-новной слой и первый слой покрытия, затем накладывают на основной слой второй слой полимерного покрытия, при этом перед приемом наложения второго слоя на кромки основного слоя, полученных при разрезании полотен, наносят ингибитор, образующий участки, не сцепляющиеся с накладываемым слоем покрытия. При этом в качестве покрытия используют пластмассу.This is achieved by the fact that in the proposed method of manufacturing a layered material, the cutting of the layers of material is carried out in two stages, first the main layer and the first coating layer are cut into parallel webs, then a second polymer coating layer is applied to the main layer, while before applying the second layer an inhibitor is applied to the edges of the base layer obtained by cutting the webs, forming sections that do not adhere to the applied coating layer. In this case, plastic is used as a coating.

Кроме того, в качестве покрытия можно использовать алюминиевую фольгу с нанесенным на нее слоем пластмассы.In addition, as a coating, you can use aluminum foil coated with a layer of plastic.

Кроме того, в качестве основного слоя используют пенопласт или волокнистый материал.In addition, foam or fibrous material is used as the base layer.

На фиг. 1 показан схематично нахлесточный шов, получаемый при соединении слоистых полотен, изготовленных по описываемому способу изготовления слоистого материала; на фиг. 2 — слоистый материал, получаемый во время осуществления способа его изготовления.In FIG. 1 shows a schematic lap seam obtained by joining laminate webs made by the described method for manufacturing a laminate; in FIG. 2 - layered material obtained during the implementation of the method of its manufacture.

Способ изготовления слоистого материала осуществляют следующим образом.A method of manufacturing a layered material is as follows.

Слоистый материал (фиг. 1), состоящий из основного слоя 1 и’ полимерного покрытия, наложенного с каждой стороны основного слоя, перемещают в направлении стрелки А и разрезают на параллельные полотна 2, при этом процесс разрезания материала проводят в два этапа. Сначала разрезают с помощью режущего приспособления, например роликовых ножей 3, на параллельные полотна основной слой 1 и один нижний слой 4 полимерного покрытия, затем накладывают на основной слой с верхней его стороны второй слой 5 полимерного покрытия, при этом перед приемом наложения последнего на. кромки основного.слоя 1 наносят ингибитор, например воск или силиконовую смесь, в виде каймы. Ингибитор при этом образует участки 6 (фиг. 2), не сцепляющиеся с накладываемым слоем 5 покрытия. В качестве покрытия используют пластмассу.The layered material (Fig. 1), consisting of a base layer 1 and a polymer coating applied on each side of the base layer, is moved in the direction of arrow A and cut into parallel web 2, while the process of cutting the material is carried out in two stages. First, they are cut using a cutting device, for example, roller knives 3, into parallel webs, the main layer 1 and one lower layer 4 of the polymer coating, then a second polymer coating layer 5 is applied to the main layer from its upper side, before being applied to the latter. the edges of the base layer 1 are applied an inhibitor, for example a wax or silicone mixture, in the form of a border. In this case, the inhibitor forms sections 6 (Fig. 2) that do not adhere to the applied coating layer 5. As a coating use plastic.

Слой 5 покрытия накладывают с помощью литьевого оборудования, помещённого над полотнами материала и подающего под давлением нагретую пластмассу через сопло (не показаны) для образования пленки.Coating layer 5 is applied using injection molding equipment placed over the material webs and supplying heated plastic under pressure through a nozzle (not shown) to form a film.

Далее на .пленку воздействует пара прокатных валков, в результате чего она сцепляется с основным слоем 1 и слоем 4 покрытия, что приводит к сое»динению параллельных полотен материа-/ ла между собой слоем 5 покрытия. 'Further, a pair of rolling rolls acts on the film, as a result of which it adheres to the main layer 1 and the coating layer 4, which leads to the jointing of the parallel material / la sheets to each other by the coating layer 5. ''

При дальнейшей подаче материал разрезают с помощью другого режущего приспособления, содержащего несколько роликовых ножей 7, установленных поперек относительно направления перемещения материала, при этом нёжи 7 разрезают материал не по'всей толщине , а лишь разделяют слой 5 покрытия на параллельные полотна.With further feeding, the material is cut using another cutting device containing several roller knives 7 mounted transverse to the direction of movement of the material, while the blades 7 do not cut the material in all thickness, but only divide the coating layer 5 into parallel sheets.

Ножи 7 по отношению к ножам 3 несколько смещены в поперечном направлении, вследствие чего параллельные разрезы в слое 5 покрытия расположены на некотором расстоянии от разрезов, выполненных ранее в основном слое 1 и в слое 4 покрытия.величина этого смещения соответствует ширине участка 6, на котором слой 5 покрытия сцепляется с основным слоем 1.The knives 7 with respect to the knives 3 are somewhat offset in the transverse direction, as a result of which the parallel cuts in the coating layer 5 are located at some distance from the cuts made previously in the main layer 1 and in the coating layer 4. The magnitude of this offset corresponds to the width of the section 6, on which the coating layer 5 adheres to the base layer 1.

Благодаря наличию участка 6 двух разрезов,слоистый материал деляется на отдельные параллельные полотна, каждое из которых имеет цель>ную полосу 8 (фиг. 1), которая образует выступающую кромку рого слоя 5 покрытия.Due to the presence of section 6 of two cuts, the layered material is divided into separate parallel webs, each of which has a target> strip 8 (Fig. 1), which forms a protruding edge of the sweeping layer 5 of the coating.

The layered material (Fig. 1), consisting of the base layer 1 and the polymer coating applied on each side of the base layer, is moved in the direction of arrow A and cut into parallel webs 2, and the cutting process of the material is carried out in two steps. First, the main layer 1 and one lower layer 4 of the polymer coating are cut into parallel blades with a cutting device, such as roller knives 3, then the second polymer coating layer 5 is applied to the base layer on its upper side, before this last n edge is applied basic layer 1 is applied inhibitor, such as wax or silicone mixture, in the form of a border. In this case, the inhibitor forms areas b (Fig. 2) that do not adhere to the applied layer 5 of the coating. Plastics are used as coatings. Layer 5 of the coating is applied using injection molding equipment, placed over the sheets of material and feeding heated plastic through a nozzle (not shown) to form a film. Next, the film is affected by a pair of rolling rolls, as a result of which it adheres to the base layer 1 and the coating layer 4, which leads to the parallelization of the parallel web webs between the coating layer 5. With further feed, the material is cut with another cutter, containing several roller knives 7 set transversely with respect to the direction of displacement and material, while the cutter 7 does not cut the material but only separates it; coating layer 5 on parallel webs. . The knives 7 with respect to the knives 3 are somewhat displaced in the transverse direction, as a result of which the parallel cuts in the coating layer 5 are located at a certain distance from the cuts made earlier in the main layer 1 and. in layer 4 of the coating. The magnitude of this displacement corresponds to the width of section b, on which layer 5 of the coating n adheres to the base layer 1. Due to the presence of section b and two cuts, the laminate is divided into separate parallel webs, each of which has an entire strip 8 (Fig 1), which forms a protruding edge of the upper second coating layer 5. Next, each web 2 is individually rolled into a roll 9. To save space and facilitate access, the web can be guided appropriately using rollers (not shown). The size of the width of the individual sheets of the laminated material can be changed, if necessary, by lateral displacement of the knives 3 and a corresponding displacement relative to the last knives 7. The non-adherent material sections 6 can also be formed by using a rolling roll which imposes a layer 5 of the coating with annular grooves (not shown) the width and location of which corresponds to the width and placement of the unlinked areas. As a result, zones without adhesion or small adhesion of layer 5 to the base layer 1 are formed. A longitudinal seam is obtained in such a way that the edge zones of the material web are located one above the other, after which the coating layers placed in zones 10 and 11 are fused by pressing and heating. In order to carry out this operation, layers 4 and 5 of the coating contain a material that is fused when heated, for example, polyethylene, and each layer may also contain layers of a different material, for example, aluminum foil coated with a layer of plastic. A foam or fibrous material, for example paper, is used as the base layer 1. When joining the two edge zones of the laminated web in one lap seam to form a longitudinal scar on the pipe, zone 12 (Fig. 1) located on the outside of the pipe is not attached at all or is attached by means of an easily breakable seam to the coating layer 4 during the heating process , since the outer edge of the web does not have a part of the inner layer, fusing during heating, of the coating layer 5 corresponding to the strip 8. This is advantageous when opening the bag with a yarn. The proposed method, together with the manufacture of a layered material, provides for its separation into narrower individual webs and reduction of technological waste during its manufacture. Claim 1.
