摘要： A device for transversely stretching a web includes a pair of pulleys arranged in the substantially same plane and rotating in the opposite directions to each other and a pair of belts running around the pulleys, respectively. The web is widthwise stretched, by gripping opposite side edges thereof by the pulleys and the belts and conveying the web in a divergent manner. At least one pair of pressing rolls are provided at an inclination relative to the belts for pressing the opposite side edges of the web onto the belts prior to being gripped between the pulleys and the belts. According to this structure, a device for transversely stretching a web is realized which is capable of effectively preventing the web from being dropped from the grip.

摘要： A transversely extending device comprises a pair of pulleys substantially disposed in an identical plane and adapted to rotate in opposite directions and a pair of belts set over the pair of pulleys, respectively. By transferring a belt-like body such that it expands in a flare shape while being held on side edge portions thereof by the pulleys and belts, a belt-like body is transversely extended. At least a pair of pressing rolls are provided inclined against the belts for pressing to the respective belts the side edge portions of the belt-like body before they are held between the respective pulleys and belts. With this construction, the transversely extending device for effectively preventing the disengagement of the belt-like body is thus realized.
