<p>The invention relates to apparatus for performing operations on a continuous web of material (D), for example a printer performing printing operations on a continuous web document, including a housing (10), an operating mechanism (13, 14) located within the housing for performing operations on the web of material, a web feeding mechanism (24, 26, 33) located within the housing for feeding the web past the operating mechanism so that the operating mechanism can perform operations on the web, and a device for use in the removal of a portion of the web on which operations have been performed. …<??>The invention is characterised in that the device for use in the removal of a portion of the web comprises a web engaging member (50) movably supported within the housing (10) for movement between a normal position in which it is spaced from the web (D) to allow free passage of the web past the operating mechanism (13, 14) and an operating position in which it engages and grips a portion of the web (D) downstream of the operating mechanism (13, 14). The device further comprises an operating member (52, 60) connected to the web engaging member (50) and located outside the housing (10) for operation by an operator to move the web engaging member (50) from the normal free passage position into the operating web engaging position, whereby the web (D) may be engaged and gripped by the web gripping member (50) while the portion of the web located downstream of the web engaging member may be torn off from the rest of the web.</p> |
