Description

Стопор располагают до иди после устройства образовани  полос пониженной прочности.The stopper is positioned before going after the device for the formation of strips of reduced strength.

На фиг. 1 схематически показан вариант осугцествлени  предлагаемого способа; на фиг. 2 - устройство, управл ющее работой стопорного устройства и устройства образовани  полос пониженной прочности .FIG. 1 schematically shows the option of extinction of the proposed method; in fig. 2 shows a device controlling the operation of the locking device and the device for forming strips of reduced strength.

Металлизированную фольгу 1 подают между цилиндрическим кар«а1сом 2 и изол ционной фольгой 5 в виде непрерывной ленты, которую на устройстве ослабл ют по всей ее ширине. Когда металлизированна  фольга совершает один полный оборот ВО.К1РУГ цилиндра, т. е. достигает нужиой длины, столор 4 останавливает металлизированную фольгу, после чего она разрываетс  по ра:нее осла бленному месту. Стопор 4 вступает в дейст1вие, как только ранее ослабленный участок начинает наматыватьс  на цилиндр 2. Благодар  этому оторванный конец фольги / остаетс  на некоторый короткий период времени между .изол ционной фольгой 3, действующей как т нущий элемент, и цилиндром 2.The metallized foil 1 is fed between the cylindrical frame and the insulating foil 5 in the form of a continuous tape, which is loosened on the device across its entire width. When the metallized foil makes one complete revolution of the VO.K1RUG of the cylinder, i.e., reaches the required length, the stopper 4 stops the metallized foil, after which it is torn in one of its dead spots. The stopper 4 comes into action as soon as the previously weakened area begins to be wound on the cylinder 2. Due to this, the severed end of the foil / remains for some short period of time between the insulating foil 3 acting as a pulling element and the cylinder 2.

Стопор 4 удерживает фольгу 1, пока цилиндр 2 не повернетс  на требуемый угол. После прекращени  действи  стопора 4 металлизированна  фольга сразу продолжает движение благода:р  трению. Длина намотки может быть увеличена до тех пор, пока металлизированна  лента сможет выдерЖать силы трени .The stopper 4 holds the foil 1 until the cylinder 2 is rotated to the desired angle. After stopping the action of the stopper 4, the metallized foil immediately continues to move due to: friction. The length of the winding can be increased as long as the metallized tape can withstand friction.

Стопор 4 содержит две покрытые резиной пластины 5, 6, которые во врем  работы устройства сжимаютс  вместе рычагами с электромагнитным приводом, сжатие может быть также осуществлено пневматически , гидравлически или другим способом. Устройство 7 образовани  полос пониженной прочности имеет несколько близко расположенных друг к другу лезвий 8, которые делают в фольге прорези, например шириной 10 HiJK и с промежутком между ними 1 мм. Лезви  8 прикреплены к валу, устанозлеаному в подшипниках, обеспечивающих возможность вращени  вала.The stopper 4 contains two rubber-coated plates 5, 6, which during operation of the device are compressed together with electromagnetically operated levers, compression can also be carried out pneumatically, hydraulically or by other means. The device 7 for the formation of strips of reduced strength has several blades 8 closely spaced to each other, which make slots in the foil, for example a width of 10 HiJK and with a gap between them of 1 mm. Blades 8 are attached to a shaft mounted in bearings that allow the shaft to rotate.

На фиг. 1 устройство 7 показано з исходном положении, когда остри  лезвий 8 расположены несколько выше металлизированной фольги. Вращению устройства преп тствует стержень 9. При подаче импульса управл ющим устройством стержень отводитс , и вал под действием сжимающей , упругой иди какой-либо другойFIG. 1, the device 7 is shown in its initial position, when the tips of the blades 8 are located slightly above the metallized foil. The rod 9 is prevented from rotating the device. When the impulse is applied to the control device, the rod is retracted and the shaft is under the action of a compressing, elastic or some other

силы поворачиваетс , дава  возможность остри м лезвий 5 коснутьс  поверхности металлизированной фольги /. При движении фольги навстречу лезви м они делают в ней прорези. После выполнени  ослаблени  устройство возвращаетс  в исходное положение, продолжа  движение по замкнутому кругу.The force is rotated, making it possible for the blades of the blades 5 to touch the surface of the metallized foil. When the foil moves towards the blade, they make cuts in it. After performing the attenuation, the device returns to its original position, continuing to move in a closed circle.

Вместе с цилиндром дл  изготовлени  изол ции вращаетс  колесо 10, поворачива  другое колесо //. На общем валу с колесом // вращаютс  кулачковые диски 12 и 13 микропереключателей, управл ющих работой устройства ослаблени  и стопорного устройства (фиг. 2). Требуемый результат управлени  получают регул.ировкой отнощени  диаметров колес 10 и 11, а также регулировкой длины выступа кулачковых дисков.The wheel 10 rotates with the cylinder to make the insulation, turning the other wheel //. On a common shaft with a // wheel, cam disks 12 and 13 of microswitches rotate, controlling the operation of the loosening device and the locking device (Fig. 2). The required control result is obtained by adjusting the ratio of the diameters of the wheels 10 and 11, as well as by adjusting the length of the cam discs.

Стопор 4 и устройство 7 могут быть размещены в Обратном пор дке по отношению к напра1вленик) движени  металлической ленты /, изображенному на фиг. 1.The stopper 4 and the device 7 can be placed in Reverse order with respect to the direction of movement of the metal tape / shown in FIG. one.
