Feeding And Cutting Unit For A Dispenser Of Paper Sheets Obtained From A Continuous Band

Abstract

A feeding and cutting unit for a dispenser of paper sheets obtained from a continuous band comprises a supporting structure (1, 2, 3) that rotatably supports a feeding roller (4) which in turn internally rotatably supports a shaft (5) parallel thereto which carries a blade (6) that during the rotation of the blade-carrying shaft (5) projects through a corresponding longitudinal slot formed in the feeding roller (4), the unit including a pair of constantly engaged end gearings formed by a first toothed wheel (7) integral with and coaxial to the blade-carrying shaft (5) and a second toothed wheel (8) formed on the supporting structure (1, 2, 3) at a position coaxial to the axis of rotation of the feeding roller (4). In this way, a simplification of the unit is achieved as well as a greater reliability and smoothness of operation guaranteed by the constant engagement whereby there are no problems of synchronized rotation of the blade-carrying shaft (5) and of the feeding roller (4) regardless of plays or wear that may rise over time.
