Abstract
In processing web material, the material is passed through a guiding arrangement which has a plurality of guide elements. In order to enable removing the guide element for repair without disturbing the web material, each of the guide elements is provided with a lifting arrangement which is concentric to the guide element and is movable from one angular position withdrawn from the path of the elongated material engaging the guide element to a second position lifting the elongated material off of the guide element so that the guide element can be axially withdrawn from the machine.
Claims20
An apparatus for guidance of elongated material, which is selected from material webs and traction mechanisms, in a web-processing machine, said apparatus including at least one guide element for guiding elongated material, a rotatable lifting mechanism for each of said guide elements, said lifting mechanism being pivoted between a first position on the guide element retracted from a region of the guide element engaging the elongated material and a second position wherein the lifting mechanism holds the elongated material at a spaced distance from the guide element, the at least one guide element being a guide drum for guiding a web material, said guide drum being connected to an insert and being removable in an axial direction together with the insert when the lifting mechanism is moved into the second position.
A method for guiding an elongated material, which is selected from a material web and a traction mechanism, in a web-processing machine, said machine having at least one guide element for guiding the elongated material, a pivotable lifting mechanism allocated to each guide element, said lifting mechanism being pivotable from a first position on the guide element outside of the region wherein the elongated material engages the guide element into a second position which holds the elongated material at a distance from the guide element, said method comprising rotating the lifting mechanism from the first position to the second position to lift the elongated material off of the guide element and then axially removing the guide element from said machine.
A system for processing elongated material selected from printing and copying, said system including a plurality of guide elements for guiding the elongated material through various changes of path, each guide element being mounted in the system for axial removal from the system, each guide element having a lifting mechanism mounted on the guide element and movable between a first position retracted from the region where the guide element engages the elongated material to a second position lifting the elongated material off of the guide element so that the guide element can be axially removed from the system without disturbing the elongated material.
An apparatus for guidance of elongated material, which is selected from material webs and traction mechanisms, in a web-processing machine, said apparatus including at least one guide element for guiding elongated material, a rotatable lifting mechanism for each of said guide elements, said lifting mechanism being pivoted between a first position on the guide element retracted from a region of the guide element engaging the elongated material and a second position wherein the lifting mechanism holds the elongated material at a spaced distance from the guide element, the lifting mechanism containing a semi-cylindrical lifting ring segment that holds a traction mechanism at a distance from the guide element when the lifting mechanism is in the second position, the lifting ring segment being connected to a rotary flange that is rotatably accepted in a frame part, the guide element being connected to an insert that is torsionally accepted within the rotary flange, and an axially interlocking mechanism being provided that axially interlocks the insert in a first position and releases the insert in an axial direction when in the second position.
