A spool for a supply of printing material, said spool comprising:
- a first part, said first part comprising a shaft on which the supply of printing material is mountable,
- a second part, said second part having an opening and being arranged to retain the supply of printing material mounted on the first part, said opening being arranged to engage said shaft,
- wherein said opening is resilient and the shaft has at least one part which extends towards the opening more than at least one other part thereof to thereby cause said opening to engage with said shaft,
- wherein said second part has a plurality of apertures arranged around and extending from said opening to provide resilience, and
- wherein said apertures at least partially extend in directions approximately tangentially to said opening.
A spool for a supply of printing materials, said spool comprising:
- a first spool part, said first spool part comprising a shaft on which the supply of printing material is mountable,
- a second spool part, said second spool part having an opening and being arranged to retain the supply of printing material mounted on the first spool part, said opening being arranged to engage said shaft,
- wherein said opening is resilient and the shaft has at least one part which extends towards the opening more than at least one other part thereof to thereby cause said opening to engage with said shaft,
- wherein said second spool part has a plurality of apertures around said opening to provide resilience, and
- wherein said apertures have a first aperture part which extends from said opening and a second aperture part extending in directions approximately to a radius of said second spool part.
A cassette comprising a spool for a supply of printing material, said spool comprising:
- a first part, said first part comprising a shaft on which the supply of printing material is mountable,
- a second part, said second part having an opening and being arranged to retain a supply of printing material on the first part, said opening being arranged to engage said shaft,
- wherein said opening is resilient and the shaft has at least one part which extends towards the opening more than at least one other part thereof to thereby cause said opening to engage with said shaft,
- wherein said second spool part has a plurality of apertures around said opening to provide resilience, and
- wherein said apertures at least partially extend in directions approximately tangentially to said opening.
A cassette comprising a spool for a rolled supply of printing material, said spool comprising:
- a first part comprising a shaft on which the supply of printing material is mountable,
- a second part comprising an opening and a plurality of apertures arranged around said opening, wherein the second part is arranged to engage said shaft and to retain a supply of printing material mounted on the first part,
- wherein the shaft has at least one part which extends towards the opening more than at least one other part thereof to thereby cause said opening to engage with said shaft, and
- wherein said apertures have a first aperture part which extends from said opening and a second aperture part extending in directions approximately perpendicular to a radius of said second spool part.
