ABSTRACT:
A support for a roll of paper or similar material. The support comprises a shaft divided into two portions (10 and 11). The inner end of the portion (11) is internally threaded to receive an externally threaded boss (1) on the portion (10) The boss (14) carries a rubber ring (17) located between two washers (16 and 18). When the two portions (10 and 11) are assembled, the ring (17) is squeezed between the washers (16 and 18) so that its diameter expands until it grips the interior of the paper roll.
