Title
(EN) PRINTER ASSEMBLY LOW FRICTION ROLLER LINER
(FR) REVÊTEMENT DE ROULEAU À FAIBLE FROTTEMENT D'ENSEMBLE IMPRIMANTE
Abstract
(EN)
The present disclosure relates to a low friction roller liner for a printer assembly that may include a core layer, a first outer layer overlying a first surface of the core layer, a second outer layer overlying the first outer layer, a first inner layer overlying a second surface of the core layer that is opposite of the first surface of the core layer, and a second inner layer overlying the first inner layer. The first outer layer and the first inner layer may include a fluoropolymer material and may have a melt flow rate of at least about 2 g/10 min at 372°C. The second outer layer and the second inner layer may include a fluoropolymer material distinct from the fluoropolymer material of the first outer layer and may have a surface coefficient of friction of not greater than about 0.2.

La présente invention concerne un revêtement de rouleau à faible frottement pour un ensemble imprimante qui peut comprendre une couche centrale, une première couche externe recouvrant une première surface de la couche centrale, une seconde couche externe recouvrant la première couche externe, une première couche interne recouvrant une seconde surface de la couche centrale qui est opposée à la première surface de la couche centrale, et une seconde couche interne recouvrant la première couche interne. La première couche externe et la première couche interne peuvent comprendre un matériau de fluoropolymère et peuvent avoir un indice de fluidité d'au moins environ 2 g/10 min à 372 °C. La seconde couche externe et la seconde couche interne peuvent comprendre un matériau de fluoropolymère distinct du matériau de fluoropolymère de la première couche externe et peuvent avoir un coefficient de frottement de surface non supérieur à environ 0,2.
