#CMT# #/CMT# The arrangement (2) has a drawing roller (9) and two pull rings (11, 12), which displaceably arranged in an axial direction of the drawing roller and pressed against the drawing roller. The pull ring (12) is adjustable in the axial direction. The two pull rings are mounted on carriages (14, 16) adjustable in the axial direction and are adjustable counter axially by a common control member (51). The control member has a threaded spindle (48) with two sections (52, 53) of opposing pitches, where the threaded spindle is pivoted at a shaft (49) and is axially adjustably coupled. #CMT#USE : #/CMT# Drawing roller arrangement for use in a folding machine. #CMT#ADVANTAGE : #/CMT# The two pull rings are mounted on carriages adjustable in the axial direction and are adjustable counter axially by the common control member, thus realizing a simple guidance of the pull rings. The arrangement minimizes heterogeneity of the wear, if the pull rings are operated tangentially to the entire width of the material web, and allows the wear to be symmetrical and avoids unequal distribution of the traction powers to cause a lateral twist of the material web. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a drawing roller arrangement. 2 : Drawing roller arrangement 9 : Drawing roller 11, 12 : Pull rings 14, 16 : Carriages 48 : Threaded spindle 49 : Shaft 51 : Common control member 52, 53 : Sections. |
