Tissue Machine, Pama, 2,320mm, 40tpd,
General technical information
Manufacturer: PAMA, Freiberg, 1958.
In production until mid of 2010, now preserved (cylinders open for avoiding moisture accumulation, lubrication verified, felts dismounted, wire still present in order to protect foils and boxes).
Hand of machine: right side
Production: 30-40 tpd of crepe paper towel 41 g/m2
Type of furnish: waste paper
Width on reel: 2,32m
Speed on yankee ca. 320-350 m/min
Yankee diameter: 3187mm, metallized in year 2001.
Yankee operating pressure: 2,5 barg
Head box with dilution zones for basis weight profiling
Long wire section: 1 wire, horizontal foil section, free fall drainage box, vacuum boxes, showers.
Press section: 2 presses (1 felt press, 1 yankee press)
Felt section: 2 felt
The paper is taken by the upper felt with the pick-up system, then goes to the felt press– consisting two press rolls – where the paper is pressed between the upper and lower felt. The lower felt has the only function to take up the humidity of the paper.
The paper remains under the upper felt and goes to the yankee press roll which presses the paper onto the yankee cylinder.
Both felt sections have Uhle-boxes, showers and manual felt tensioning and regulation systems.
Dry section: 8 drying cylinders. Canopy hood on the cylinders. Cylinder diameter: 1,5 m ca.
Operating pressure:2,5 barg.
3 doctor blades: detaching blade, creping blade, cleaning blade. Pneumatic system.
No coating chemicals necessary, except modest quantities of realease agent mixed together with the stock.
Overhead monorail crane for spool handling: ABUS
Steel structure and manual hoists: drive side and operator side for maintenance works. Walkways and stairs around the paper machine.
PM mechanical drives Yankee cylinder: CC motor and gear box
Dry section and pope reel: CA motor. This part is equipped with belts and conical wheels. Electromechanical system control relative position between belts and conical wheels and so control the speed of cylinder. Press roll: CC motor and gear box
Wire roll CA: motor and gear box
