Tape



Different kinds of tapes

  • Criticality

The features of the tapes may vary considerably (thickness, color, compressibility, etc.) requiring them to be handled quite differently

  • Solution

A complex system, consisting of a rollers guiding mechanism, was designed for guiding any kind of tape appropriately, according to its different characteristics

Air bubbles

  • Criticality

When the double-sided adhesive tape is manually applied on the sleeve, air bubbles are entrapped underneath.
This bubbles can lead to printing problems, such as plate lifting and dirty printing.

  • Solution

Our system performs a smooth application of the tape and plates, in order to avoid air bubbles entrapment, by using a special roller exerting a calibrated and correct pressure, especially when combined with a double-sided adhesive tape with a specific irregular pattern embossed surface, like our BS MOUNT series.

Streaks

  • Criticality

The manual uneven pressure exerted by the operator on the tape and on the plate inevitably causes streaks.
Double-sided adhesive tapes are extremely sensitive to pressure and therefore, when this is exerted manually, the adhesion may vary from one area to another resulting inadequate somewhere.

  • Solution

The TPMM incorporates a roller, covered with special rubber especially designed and developed, our PRT system, which is capable of adjusting itself to all 3D reliefs and avoids the uneven distribution of the pressure.
The system features a special mechanism which prevents any bending or deformation of the roller during the application.

Stripping of the liner

  • Criticality

Liner stripping is rather time consuming and also awkward as the electrostatic reactions that ensue make it difficult for the operator to peel the liner off his hands. The waste is also very voluminous.

  • Solution

The TPMM ensures that the liner is automatically stripped off from the double-sided adhesive tape in the correct way and that the liner itself is rewound neatly.
The problems connected with electrostatic reactions and voluminous waste are therefore solved.

Tape cutting

  • Criticality

After having been applied on the sleeve, the double-sided adhesive tape is cut off manually directly on the sleeve itself.
This operation may cause damage to the sleeve and also consequent adhesive residues remaining on the sleeve.

  • Solution

The TPMM cutting system calculates exactly the length of the tape to be used to wrap the sleeve according to the data provided by the special sensor, and it automatically cuts the tape away from the sleeve on the side shelf.

Edges alignment

  • Criticality

When the tape is applied manually, some gaps inevitably appear between the strips because it is impossible to conduct this operation with absolute precision. 
These gaps may have different shapes and they will create problems during the printing process.

  • Solution

A composite system identifies and guides the edges of the tape and controls the operation for perfect alignment of any type of tape, apart from its condition.
