Data Sheet of Used COEMTER TER WIND 84120 45-45/N ROLL

Ref.: 300044769

Brand: COEMTER

Year: 2003

Other Specifications:

The T-Wind 84120 45-45/N Roll machine has been specially designed for the continuous production of single-lane, bottom-welded or triple-welded bags on rolls.

The excellent welding, strong and resistant provided by the machine is made by a "tension free" welding system and a cooling loop for a complete shrink wrapping.
The rotary knife pre-slitting system, aided by a motorized loop and an experienced four-station rewinder provides rolls of bags with a "clean" pre-slit line, and "very smooth" when removing bags from the roll.

THE MACHINE CONSISTS OF THE FOLLOWING MODULES:

PRE-CUTTING SYSTEM by rotating blade with total stability of the pre-cutting position with respect to the sealing.
Fast cutting adjustment system (exclusive Coemter) that extends the life of the blade and drastically reduces downtime.

Continuous WELDING BODY with constant heat sealing system at low temperature.
Two floating main welders, with lateral expansion.
Wire welding with continuous tensioning system.
System of soft silicone pads (interchangeable without disassembly), driven by chain with pneumatic tensioner and guided peripherally on the drum to avoid stretching of the chains, which are also guided along their entire length.
Adjustable film input and output tension on the drum.
Tension-free loop, at the drum exit, for weld cooling with automatic height control.
Manual mechanical register (to register pre-cutting with welding).
Drive by AC motor and frequency inverter.

Motorized DOUBLE TRIANGLE FOLDER, with AC motor and frequency inverter, also includes compensator for rewinder speed control.

FOUR-STATION REWINDER, with electro-pneumatic drive and electronic control.
Number of bags per reel preselectable by electronic counter.
Drive of the rewinding clamps by AC motor with frequency inverter and electromagnetic clutches.
Electrical braking and positioning system of the rewinding clamps (Coemter patented system).
Electronic roll separation point determination (without spark gap meter).
Roll separation by simultaneous turning of rewinding clamps, aided by "Kunfú" mobile paddle stroke.
Detector of "extracted roll" and "gripper in position", with machine stop in case of anomaly.
Automatic machine stop in case of overload in the drum turning transmission or in case of roll non-separation.
Drum turning transmission can be disengaged manually.
Slow rewinding by manual push button.
