Description

Изобретение относитс  к области обработки полимерных пленок и может быть использовано дл  получени  пол роидов.The invention relates to the processing of polymer films and can be used to produce polys.

Известно устройство дл  раст жени  полимерных пол роидных пленок, содержащее неподвижный и подвижный в осевом направлении захваты дл  удержани  торцов раст гиваемой пленки и продольные направл ющие.A device for stretching polymeric polar films comprising fixed and axially movable grippers for holding the ends of the stretchable film and longitudinal guides is known.

Однако в известном устройстве имеет место больш.а  поперечна  усадка пленки, .вследствие чего значительна  ее часть оказываетс  браком.However, in the known device there is a large transverse shrinkage of the film, as a result of which a significant part of it is a marriage.

С целью устранени  поперечной усадки пол роидной пленки и повыщени  ее качеств предлагаемое устройство снабжено двум  упругими элементами и жестко св занными с ними боковыми захватами, перемещающимис  по продольным направл ющим.In order to eliminate the transverse shrinkage of the poloid film and enhance its qualities, the proposed device is equipped with two elastic elements and rigidly connected lateral grips moving along the longitudinal guides.

На чертеже показано предлагаемое устройство .The drawing shows the proposed device.

Оно содержит неподвижный захват / и подвижный в осевом направлении захват 2, в которых закрепл ютс  торцы раст гиваемой пленки 3, а также два упругих элемента 4, свободна  длина которых равна свободной длине пленочной заготовки. С элем.ентами 4 жестко св заны симметрично расположенные боковые захваты 5, перемещающиес  по продольным направл ющим 6.It contains a fixed grip / and an axially movable grip 2, in which the ends of the stretchable film 3 are fixed, as well as two elastic elements 4, the free length of which is equal to the free length of the film blank. The elements 4 are rigidly connected by symmetrically arranged side grippers 5, moving along the longitudinal guides 6.

Устройство работает следующим образом.The device works as follows.

Раст гиваемую пленку 3 закрепл ют за торцы в захватах 1 и 2, а за боковые кромки в захвата.х 5. При перемещении подвижного захвата 2 происходит раст жение пленки и одновременно упругих элементов 4, при этом жестко св занные с ними боковые захваты 5 перемещаютс  по направл ющим 6 и не дают илеике сесть в поперечном направлении. Сопротивление движению боковых захватов воспринимаетс  упругими элементами и на пленку не передаетс .The stretchable film 3 is fixed to the ends in the grips 1 and 2, and to the side edges in the grips 5. When the movable gripper 2 is moved, the film and the elastic elements 4 simultaneously stretch, while the lateral grips 5 rigidly connected with them move along the guides 6 and do not allow the ileik to sit in the transverse direction. The resistance to movement of the side grippers is perceived by the elastic elements and is not transmitted to the film.

Предмет и з о б р е т е н и  Subject and title

Устройство дл  раст жени  полимерных пол роидных пленок, содержащее неподвижiibiii и подвижный в осе,вом направлении захваты д,1Я удержани  торцов раст гиваемой пленKii и продольные направл ющ1 е, отлича1ощи,еес  тем, что, с целью устранени  поперечной усадки пленки и повышени  ее качества, оно снабжено двум  упругими элементами и жестко св занными с ними боковыми захватами, перемещающимис  по продольным направл ющим .A device for stretching polymeric polar films containing a stationary and movable axially gripping g, 1 I retention of the ends of the stretchable film K i and a longitudinal guide, which is different in that, in order to eliminate the transverse shrinkage of the film and improve its quality It is provided with two elastic elements and rigidly connected lateral grippers moving along longitudinal guides.
