  2. Tape wrapper OT-16-500 - 2 pcs
  3. Traction device TG-1600 - 1 pc.
  4. Receiving device PTU-1800 - 1 pc.
  5. Straightener - 1 pc
  6. Electrical equipment with a controller and an operator panel based on Siemens - 1 pc.


Tangential wrapper for 16 tapes with a diameter of circles of insulating material up to 500 mm. consists of a head with 16 plates, a protective fence, an asynchronous electric motor with an encoder and forced cooling, a pneumatic brake device, belt tension regulators and sensors for breaking and ending the tape (for each circle), a sound and light signaling device (andona), a control panel ( for 8 buttons + space for the OP-77A panel), Micromaster 440 electric drive for the electric motor with encoder and profibas panel, braking resistor.

Design Features

Support rollers are installed at the entrance to the wrapper and at the exit from the wrapper to hold the insulated core and eliminate its runout.

The tension of paper tapes is adjusted by adjusting the tension constancy mechanisms when installing a roll with paper of various widths and thicknesses.

A pneumobrake is provided to quickly stop the wrapper head when the tape break lock is triggered.

The buttons and the operator panel on the control panel are purchased and installed by the Customer.

The cover of the wrapper guard is opened by a pneumatic cylinder.
