摘要： In a paper making machine a porous support belt travels together with the web over a drying cylinder and leaves the cylinder at a point of removal. A suction box provided in the region of the web removal has a suction zone which is defined by means of two yieldable sealing strips which extend transversely to the direction of travel of the web, and each is supported in a sealing strip holder. The distance between each sealing strip holder and the outer surface of the drying cylinder amounts to at least 30 mm, and each of the yieldable sealing strips has, in its normal condition of operation, such an inherent stiffness that the sealing strip remains substantially free of deformation in the event of a difference in pressure of 0.01 to 0.1 bar between the suction zone and its surroundings.

摘要： Apparatus for introducing a felt belt into the press section of a paper making machine. The endless loop belt is supported on a pair of support bars or, in an alternate embodiment, on a single support bar, which are provided on a frame comprised of two side parts held together by the support bars. Both of the support bars are located outside the belt loop. The belt loop is pulled up and draped over one or both of the support bars defining one or more folded regions of the belt at one or both of the support bars, which shortens the suspended length of the belt. A clamping device, typically secured to the side parts of the frame, clamps the folded region of the belt to the support bar while the belt is introduced into the press section. After the belt has been introduced into the press section, the device including its frame is unclamped from the folded regions of the belt and removed from the machine.
摘要翻译： 用于将毛毡带引入造纸机的压榨部的装置。 无端环带被支撑在一对支撑杆上，或者在替代实施例中，在单个支撑杆上，该支撑杆设置在由支撑杆保持在一起的两个侧部组成的框架上。 两个支撑杆位于皮带环之外。 带环被拉起并且悬挂在一个或两个支撑杆上，在一个或两个支撑杆上限定带的一个或多个折叠区域，这缩短了带的悬挂长度。 通常固定到框架的侧部的夹紧装置将带的折叠区域夹在支撑杆上，同时带被引入压榨部。 在带被引入压榨部之后，包括其框架的装置从带的折叠区域松开并从机器上移除。
