Abstract
A roll dispenser is arranged to support a roll of packaging material, and includes a chuck assembly with a first chuck unit that includes a first plug received in a first axial end of a core of the roll, a first shaft fixed to the first plug, a first mount brought into engagement with the first shaft, and a first brake connected to the first plug and the first mount to establish friction between the first plug and the first mount. A first handle assembly may adjust a first compressive force applied axially between the first mount and the first shaft to regulate the friction between the first plug and the first mount. The chuck assembly also may include a second chuck unit received in a second axial end of the core for additionally supporting the roll of packaging material.
Claims21
A roll dispenser for supporting a roll of packaging material, the roll dispenser comprising:
- a base;
- and
- a chuck assembly including a first chuck unit, wherein the first chuck unit comprises:
- a first mount mounted to the base such that the base limits rotation of the first mount mounted thereto;
- a first plug configured to be inserted in a first axial end of a core of the roll of packaging material and locked into rotation with the core;
- a first brake operably associated with the first plug and the first mount so as to establish friction therebetween that resists rotation of the first plug with respect to the first mount as the packaging material is pulled from the roll;
- and
- a spring element operably connected to the first brake, the spring element configured to exert a tensile force in an axial direction for regulating the friction between the first mount and the first plug.
A base for a roll dispenser configured to support a roll of packaging material, the base comprising:
- a base support extending in a longitudinal direction;
- and
- a pair of supports extending transversely from the base support, the pair of supports each defining a first end and a second end, wherein the first end of each of the pair of supports is mounted to a first surface of the base support,
- wherein at least one slot is formed adjacent to the second end of each of the pair of supports, and
- wherein the at least one slot of a first support of the pair of supports is configured to receive the first mount of the first chuck unit and the at least one slot of a second support of the pair of supports is configured to receive the second mount of the second chuck unit to thereby support the chuck assembly.
A system for dispensing packaging material from a roll arranged on a roll dispenser, the system comprising:
- a base;
- a chuck assembly including a first chuck unit, wherein the first chuck unit comprises:
- a first mount mounted to the base such that the base limits rotation of the first mount mounted thereto;
- a first plug configured to be inserted in a first axial end of a core of the roll of packaging material and locked into rotation with the core;
- a first brake operably associated with the first plug and the first mount so as to establish friction therebetween that resists rotation of the first plug with respect to the first mount as the packaging material is pulled from the roll;
- and
- a spring element operable connected to the first brake, the spring element configured to exert a tensile force in an axial direction for regulating the friction between the first mount and the first plug;
- and
- the roll of packaging material being supported by the base with the first plug inserted into the core.
