ABSTRACT:
An apparatus is provided for accurately guiding and treating textile strips of great width using a quasi-continuous roll which does not bend. The roll is used for guiding material presented in strip form, in particular a textile material which is in contact with a peripheral portion of the roll. The roll is sub-divided into tubular segments attached to one another by flanges supported by an inner ring of a ball bearing. An outer ring of the ball bearing is fixed in a collar integral with a support. In an angular region other than the one which is in contact with the material, the support, made from thin and flat sheet steel, extends radially outwardly to a region of attachment to the frame.
