摘要： For levelling webs of paper (3) gaps (20) are provided, each defined by a deflection roll (17) and a stationary bending face (16). For changing the wrap angle at the bending face (16) and also for non-bended passage of the web (3) through the device (1) the deflection roll (17) is transferable into varying positions powered by a positioning device (30). Thereby high speed operation with reliable function and simple construction are achieved.

摘要： An apparatus comprising two lateral guide devices guiding the paper web at the longitudinal edges of the endless paper web, and a deflection means is provided. With the aid of the deflector the paper web is deflected at least once from its direction of movement to increase the stiffness of the paper web while the paper web is moving between the lateral guide devices. Because of that, the paper web is prevented from ascending the lateral guide devices and a damage to the paper web is avoided when the paper web comes into lateral contact with the lateral guide device.

摘要： An apparatus (1) for transversal drawing a film (2) in motion, has a pair of rollers (3, 4) rotating on parallel axes and fitted with toothed surface profiles (5, 6) that overlaps without touching each other. The profiles define a wavy passage (7) for the film, and rounded tips of the toothed profiles (5, 6) of the two rollers (3 and 4) define the points of application of the drawing action on the film (2).

摘要： A device for conveying a carrier tape by holding both sides with pressing rollers and drive rollers that rotate in opposite directions. The drive rollers have large-diameter portions and small-diameter portions so that the large-diameter portions are formed on inner sides of the circumferential surfaces of the drive rollers and the small-diameter portions are formed on outer sides thereof; and the pressing rollers have small-diameter portions and large-diameter portions so that the small-diameter portions are formed on inner sides of the circumferential surfaces of the pressing rollers and the large-diameter portions are formed on outer sides thereof. Both side edges of the carrier tape are pressure-held and conveyed by the pressing rollers and drive rollers with the large-diameter portions of the pressing rollers pressing the side edges onto the small-diameter portions of the drive rollers, thus curving the carrier tape in its width direction and preventing sagging of the carrier tape across the width.

摘要翻译： 用于通过将两侧保持在相反方向旋转的按压辊和驱动辊来传送载带的装置。 驱动辊具有大直径部分和小直径部分，使得大直径部分形成在驱动辊的圆周表面的内侧上，并且小直径部分形成在其外侧上; 并且压辊具有小直径部分和大直径部分，使得小直径部分形成在按压辊的圆周表面的内侧上，并且大直径部分形成在其外侧。 载带的两个侧边缘被压辊和驱动辊压力保持并被输送，其中大直径部分的压辊将侧边缘压到驱动辊的小直径部分上，从而弯曲载带 在宽度方向上，防止载带在整个宽度上的下垂。
