1. Apparatus for dispensing flexible sheet material wound on a hollow core having a substantially horizontally disposed axis, said apparatus comprising:
- an end cap attached at each end of said core including an axially disposed spindle portion and an annular base connected to said spindle portion by a radially extending web, said annular base having an outwardly facing surface for mounting the adjacent end of said core and an inwardly facing surface concentrically spaced from said spindle;
a pair of oppositely spaced end supports, each engaging a respective one of said end caps to provide vertical support thereto; and
at least one of said end supports having a body only the upwardly facing portion of which defines a bearing surface in gravity-induced frictional engagement with the adjacent portion of said inwardly facing surface of said end cap.

Abstract
A device for rotatably supporting a roll of flexible sheet material having trunnions at the ends is provided with structure forming a friction brake to effectively control overspin of the roll during dispensing of the sheet material. The device involves an end support particularly configured to provide a bearing surface formed of resilient, high friction material effective to engage a portion of an end cap forming a roll trunnion, whereby the braking action provided by the bearing surface is directly proportional to the weight of the roll.

11. Apparatus for dispensing sheet material wound on a hollow core having a substantially horizontally disposed axis and journalled for rotation at each end by an end cap including an axially disposed spindle and an annular base having an outwardly facing surface engaging said core and an inwardly facing surface concentrically spaced from said spindle, said apparatus including an end support comprising:
-
a fixed body having an opening extending parallel to the axis of said core for reception of said spindle; and a substantially arcuate bearing surface on said body concentrically spaced from said opening and extending through the upper quadrants of said body for gravity-induced frictional engagement with said inwardly facing surface of said end cap. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
