Claims14
A device for use in connection with a fabric, having a cross machine width, in a former a press section of a paper machine, the device comprising:
- a subassembly accomplishing a guiding function of the fabric and the device further comprising at least one subassembly which performs a spreading function and a cleaning function across the entire cross machine width of the fabric and wherein the subassemblies form a single device;
- wherein the subassembly accomplishing the guiding function comprises an automatic guide and a guide roll for guiding the fabric, the automatic guide for guiding the fabric having linear guides, and a movement base arranged to provide automatic guidance;
- and
- the at least one subassembly which performs a spreading function and a cleaning function comprises a curved spreader roll for spreading the fabric, and a suction unit for cleaning the fabric.
A device for use in connection with a fabric in a former or a press section of a paper machine, the device comprising:
- a suction unit part having portions defining a suction chamber;
- at least one suction pipe extending from the suction chamber;
- a first bendable rib and a second bendable rib connected to the suction unit part to define a slot therebetween in communication with the suction chamber;
- a spreader roll mounted to the suction unit part upstream of the slot, the spreader roll being adjustable to be curved;
- a guide roll mounted to the suction unit part downstream of the slot, wherein the device is positioned such that the fabric passes over the spreader roll, across the first rib, the slot, and the second rib, and across the guide roll, and
- wherein the suction unit, the spreader roll and the guide roll form a single device incorporating an automatic guide for guiding the fabric having linear guides, and a movement base arranged to provide automatic guidance of the fabric.
