    • A heat and pressure roll fusing apparatus for fixing toner images to copy substrates, the toner being made of a thermoplastic resin. The apparatus includes an internally heated fuser roll cooperating with a back-up or pressure roll to form a nip through which the copy substrates pass with the images contacting the heated roll. The heated fuser roll is characterized by an outer layer or surface which by way of example is fabricated from silicone rubber. Sheet removal or supporting member in the form of flexible finger structures are provided. The fingers contact the surface of the heated fuser roll and therefore are constructed so as to preclude damage to the soft fuser roll surface should they tend to gouge it. In operation the fingers are sufficiently flexible so that when a misstrip occurs they can be deflected out of contact with the fuser roll and partially rotated thereby. Each finger structure may have either a single finger or two fingers. The fingers are mounted for 360.degree. of rotation partially by the heated fuser roll and, in part, manually.
    • 一种用于将调色剂图像定影成复制基板的热压辊定影装置,调色剂由热塑性树脂制成。 该设备包括内部加热的定影辊,其与备份或压力辊协作以形成辊隙,复印基板通过该辊隙与图像接触加热辊。 加热的定影辊的特征在于外层或表面,其例如由硅橡胶制成。 提供了以柔性指状结构形式的片材去除或支撑构件。 指状物接触加热的定影辊的表面,因此被构造成如果它们倾向于将其熔化,则防止对软熔剂辊表面的损伤。 在操作中,指状物具有足够的柔性,使得当发生错误时,它们可以偏转与定影辊脱离接触并部分旋转。 每个手指结构可以具有单个手指或两个手指。 手指通过加热的定影辊部分地安装360度旋转,并且部分地被手动地安装。
