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.

Dependent claims

A guiding device using a rotary roll, comprising:

a frame;
a roll having an axis and two axial ends, and comprising an axial succession of at least two roll segments, each having two opposing axial ends and being rigidly connected to each other;
an axial gap defined between said two opposing axial ends of said at least two successive segments, at least one of the opposing ends being tubular;
an annular recess which is formed to extend within said at least one tubular opposing end and opens radially outwardly to be in communication with said axial gap, said recess having a cylindrical inner wall;
a bearing having an inner ring mounted around said cylindrical inner wall of said recess, an outer ring and a support plate, said outer ring being supported, at least indirectly, by said frame by way of said support plate which extends radially outwardly through said gap;
wherein said bearing is axially longer than said axial gap and projects axially into said tubular opposing end.
