Description

Известен способ получени  бумаги повышенной раст жимости путем пропускани  влажного полотна бумаги между гладким валом и бесконечной резиновой лентой, в результате чего бумага получает мелкий креп.A known method of producing paper of increased extensibility is by passing a wet sheet of paper between a smooth roller and an endless rubber band, with the result that the paper gets a fine crepe.

Недостатками известного способа  вл ютс  большие напр жени  в резиновой ленте при работе и большие габариты устройства, дл  осушествлепи  способа.The disadvantages of this method are the large stresses in the rubber band during operation and the large dimensions of the device for carrying out the method.

Предложенный способ лишен этих недостатков. Сущность изобретени  заключаетс  в том, что резинова  бесконечна  лента армирована кардотканью на стороне, котора  не касаетс  бумаги.The proposed method is devoid of these disadvantages. The essence of the invention is that the rubber endless ribbon is reinforced with card-fabric on the side that does not touch the paper.

Бумага, полученна  по предложенному способу имеет повышенный показатель раст жимости и лучшие динамические свойства, что особенно важно дл  мешочной бумаги.Paper produced by the proposed method has an increased index of extensibility and better dynamic properties, which is especially important for bag paper.

На чертеже изображена принципиальна  с.хема воздействи  резиновой армированной кардотканью ленты на бумажное полотно.The drawing shows the principal scheme of the effect of rubber tape-reinforced cardofabric on a paper web.

При попадании бумажного полотна / с определенной влажностью между резиновой лентой 2 и обогреваемым валом . вследствие того, что (wrfe) остаетс  равным () и следовательно (cd сжимаетс  до (), возникает сжимающее усилие со стороны ленты на полотно бумаги.In case of contact with the paper web / with a certain humidity between the rubber band 2 and the heated roller. due to the fact that (wrfe) remains equal to () and consequently (cd is compressed to (), a compressive force arises from the side of the tape onto the paper web.

В результате-бумага получает мелкий креп (микрокреп) и имеет повышенный показатель раст жимости (10-12%).As a result, the paper gets a shallow crepe (microcrep) and has an increased stretch index (10-12%).

Параметры процесса следующие:The process parameters are as follows:

1)влажность (относительна ) бумажного полотна 40-50%;1) humidity (relative) of paper web 40-50%;

2)температура обогреваемого вала 100°;2) the temperature of the heated shaft 100 °;

3)твердость резиновой ленты 45-50 по Шору.3) hardness of rubber tape 45-50 Shore.

Резинова  лента 2 армирована кардотканью 4 со стороны, противоположной прилеганию бумажного полотна /, и приводитс  в ведущим валом 5.The rubber tape 2 is reinforced with a card-woven 4 on the side opposite to the fit of the paper web /, and is driven in the drive shaft 5.

№ 140674 Предмет изобретени № 140674 The subject invention

Способ получени  бумаги повышенной раст жимости, состо щий в фопускании влажного полотна бумагп между гладким валом и бесконечной резиновой лентой и отличающийс  тем, что, с целью уменьшени  напр жепий в резиновой ленте и габаритных размеров устройства дл  получени  такой бумаги, резинова  бесконечна  лента применена армированной кардотканью на стороне, не касающейс  бумаги.A method for producing paper of increased extensibility, consisting in placing a wet web of paper between a smooth shaft and an endless rubber band and characterized in that, to reduce the stresses in the rubber band and the overall dimensions of the device for making such paper, the rubber endless band is applied with a reinforced cardofabric. on the side not touching the paper.
