Abstract
Disclosed is a device for inserting a continuous tape. A system comprises a first module (60) and a second module (62). Two traction means (66, 68) can be connected to one another on the intersection (64) and can be detached again. A gripper device (78) transports a continuous tape from the input section (70) of the first module (60) to the output section (72) of the second module (62) when the traction means (66, 68) are connected. The invention also relates to a combined monitoring device.

Apparatus for threading a continuous web into a device arrangement having a first module (60) and having at least one second module (62) that are connectable to and detachable from one another at an interface (64) and that are successively traversed by the continuous web,
- whereby a traction means (66, 68) with an appertaining drive unit (80, 84) is provided in each module (60, 62),
- a gripper device (78) for gripping a beginning section of the continuous web is attachable to the traction means (66, 68) with the assistance thereof, the continuous web being pulled with the assistance of said gripper device from an input section (70) to an output section (72) of the respective module (60, 62) given the movement of the traction means (66, 68),
- and having a connector device (100) with which the traction means (66, 68) of the two modules (60, 62) residing opposite one another at the interface (64) are connectable to and detachable from one another,
- whereby the gripper device (78) transports the beginning section of the continuous web from the input section (70) of the first module (60) up to the output section (72) of the second module (62) in the connected condition of the traction means (66, 68).
Apparatus according to one of the preceding claims, characterized in that the connector device (100) contains a first crossbeam (102) and a second crossbeam (104) that are connected to the first traction means (66) or, respectively, to the second traction means (68), whereby the two crossbeams (102, 104) are detached from one another in the detached condition of the modules (60, 62), and the two crossbeams (102, 104) are connected to one another in the connected condition of the modules (60, 62).
Apparatus according to one of the preceding claims, characterized in that the respective crossbeams (102, 104) are accepted such in the modules (60, 62) in the detached condition of the modules (60, 62) that they do not project beyond the limiting plane of the modules (60, 62) facing toward one another.
Apparatus according to one of the preceding claims, characterized in that at least one of the crossbeams (102) is seated swivellable around a swivelling axis (118), whereby a swivelling of the crossbeam (102) ensues essentially length-neutral for the respective traction means (66).
Apparatus according to one of the preceding claims, characterized in that the respective crossbeams (102, 104) are arrested in their position in the detached condition of the modules (60, 62).
Apparatus according to one of the preceding claims, characterized in that mechanical actuation elements corresponding to one another can be actuated from the side of only one module (60) for connecting the two crossbeams (102, 104).
Apparatus according to one of the preceding claims, characterized in that the connector device (100) holds the gripper device (78).
Apparatus according to one of the preceding claims, characterized in that the first module (60) and the second module (62) respectively contains a drive unit (80, 84) the winds the respective traction means (66, 68) onto a wind-up reel (82, 86) or unwinds said traction means from said wind-up reel.
Apparatus according to one of the preceding claims, characterized in that a first monitoring unit (92) monitors at least one of the traction elements (68) for upward transgression of a maximum tensile stress.
Apparatus according to one of the preceding claims, characterized in that a second monitoring device (94) monitors at least one of the traction elements (68) for downward transgression of a minimum tensile stress.
Apparatus according to one of the preceding claims, characterized in that a compression spring is respectively employed as first and second spring.
Apparatus according to one of the preceding claims, characterized in that means (2040 are provided at the frame (162) with which the frame is displaceable relative to a rigid frame of the device in order to [ . . . ] the combined monitoring unit (160) to the length of the traction means (66).
Monitoring device according to one of the preceding claims 38 through 46, characterized in that means (204) are provided at the frame (162) with which the frame is displaceable relative to a rigid frame of the device in order to [ . . . ] the combined monitoring unit (160) to the length of the traction means (66).
Apparatus according to one of the preceding claims, characterized in that the first module (60) is a printer module or a copier module and the second module (62) is a fixing module containing a fixing facility.
Printing system or copying system comprising a first module (60) containing a printing device and comprising at least one second module (62) containing a fixing device that are connectable to and detachable from one another at an interface (64),
- whereby a traction means (66, 68) is provided in each module (60, 62), with whose assistance a gripper device (78) for gripping a beginning section of the continuous web can be transported from an input section (70) up to an output section (72) of the respective module (60, 62),
- and comprising a connector device (100) with which the traction means (66, 68) of both modules (60, 62) residing opposite one another at the interface (64) are connectable to and detachable from one another,
- whereby, in the connected condition of the traction means (66, 68), the gripper device (78) transports the beginning of the continuous web from the input section (70) of the first module (60) up to the output section (72) of the second module (62).
Module as part of a printing or copying system,
- whereby the module (60) is connectable to and detachable from a further module (62) at an interface (64);
- comprising a traction means (66) arranged in the module (60), with whose assistance a gripper device (780 for gripping a beginning section of the continuous web can be transported from an input section up to an output section of the module;
