Characteristics: 
1. The structure is symmetrical, can load two raw paper rolls at the same time, can change the paper roll without stopping the machine. Total electrical control over the operation of tightening, loosening, up-down, moving for center, left and right.
2. Effective working width: 1400, 1600, 1800, 2000mm
3. Max. raw paper dia: Ø1600mm
4. Min. raw paper size: Ø400mm×900mm
5. Max. loading of single arm: 1500kg.
6. Each roll stand has two paper roll sending rails, two paper roll up dollys. Rail is made from the welding of the 12# channel steel and direction-leading pole. The dolly is made from 12# channel steel, the length of the rail is 4500mm.
7. Use disk model brake, handle and electrical model are optional.
8. The clip head is cast-iron finial model or automatic double expanded model. (optional)
9. Electrical elements are centralized controlled, this highly improves the production efficiency.  
Technological parameters:

2. Paper roll length range: Max.: 1600mm   Min.:900mm
3. Paper roll diameter range: Max.: 1400mm   Min.:400mm
4. Single side max. load: 1500kg.
5. Motor power: (all are planet cycloid motor)
1) Clip motor: 0.75KW   4units   380V    50HZ
2) Up and down motor: 2.2KW   1unit  380V  50HZ
Paper roll up-dolly and rail:
1. There is direction-leading wheel on the dolly, which can send the paper roll stably.
2. Each roll stand has two paper roll sending rails, two paper roll up dollys, it can load the paper roll in two sides at the same time.
