Description

Известно устройство дл  ширени  шинного корда, состо щее из криволинейного стержн  и концевых опор.A device for spreading tire cord is known, which consists of a curved rod and end supports.

В процессе этой операции, выполн емой дугой в виде стального круглого стержн , изогнутого по дуге окружности, поперечные нити корда (основа полотна) подвергаютс  усиленному нат жению в центре (по оси полотна), остава сь свободными от нат жени  на периферии шинного корда.During this operation, performed by an arc in the form of a steel round rod curved along the arc of a circle, the transverse cords of the cord (the base of the web) are subjected to increased tension in the center (along the axis of the web), leaving them free from tension at the periphery of the tire cord.

Предлагаемое устройство дл  ширени  шинного корда отличаетс  от известных тем, что стержень дуги выполнен из шарнирно соединенны между собою роликовых звеньев. Конструкци  эта, в сочетании с упругой резиновой рубашкой, нат нутой на стержень, допускает свободное изменение кривизны дуги, обеспечивающей равномерность нат жени  шинного корда, независимо от его марки.The proposed device for tire tire width differs from the known ones in that the rod of the arc is made of hingedly connected roller links. This structure, in combination with an elastic rubber jacket tensioned on the rod, allows for a free change in the curvature of the arc, which ensures uniform tension of the tire cord, regardless of its brand.

Регулировка ширительной дуги, обеспечиваема  эластичной рубашкой , производитс  плавным изменением ее формы, а не изменением угла обхвата, примен емого при известных методах ширени  шинного кордаThe adjustment of the widening arc, provided by the elastic jacket, is made by smoothly changing its shape, and not by changing the girth angle used in the well-known methods of widening tire cord

Описываемое устройство дает экономию кордного полотна и повышение качества каландрировани  за счет интенсивности ширени  и получени  равномерных зазоров между нит ми.The described device saves the cord web and improves the quality of calendering due to the intensity of the width and obtaining uniform gaps between the threads.

На фиг. 1 изображена схема дуги с регулируемы.м радиусом кривизны; на фиг. 2 - разрез по А-А на фиг. I.FIG. 1 shows an arc diagram with adjustable m. Radius of curvature; in fig. 2 is a section along A-A in FIG. I.

Конструкци  устройства дл  ширени  шинного корда состоит из стального, изогнутого по дуге, круглого стержн  /, содержащего шарнирно закрепленные между собою роликовые звень  2, которые, через шариковый подшипник 3 и ролики 4 бочкообразной формы, соединены обп1ей эластичной резиновой рубашкой 5. Концевые звень  6 (цапфы), выступаюшие за пределы рубашки, шарнирно св заны с гайками-ползунами 7, закрепленными на подвижных, регулируемых ходовым винтом . панел х 9.The device for spreading tire cord consists of a steel, arc-curved, round rod / containing roller links 2, which are hinged between themselves, which, through a ball bearing 3 and barrel-shaped rollers 4, are connected by an elastic rubber jacket 5. The end links 6 ( pins), protruding beyond the jacket, are pivotally connected with the slider nuts 7 fixed to the movable, adjustable propeller. panel x 9.
