ABSTRACT:
The disclosure relates to a web roll retainer for retaining a web roll and for maintaining constant resistance to rotation of the roll as the web is withdrawn. The web roll retainer includes an axial support member, a roll end support mounted at each end of the support bar in non-rotational relation to the support bar and end support holding means for maintaining the end supports in fixed axial relation on the support bar. Each end support includes an annular bearing surface for supporting a web roll extending between the end supports and for providing constant resistance to web roll rotation through friction resulting from the gravitational force between the web roll and the end support annular bearing surfaces.
