CTBA - Automatic positioning knives
SLITTING HEAD WITH AUTOMATIC KNIVE'S POSITIONING
Important innovations presented at Euroblech 2014
During the last edition of the important exhibition which was held in Hanover from 21 to 25/10/2014, BOLLINA SRL presented an important and absolute news: a sslitting head with a new system for the automatic positioning of the circular knives.
The technical solution developed by BOLLINA is not a copy from the other solutions already present on the market but a new and different project because it's conceived and designed to combine the advantages of the automatic positioning to the ability to place every knives upper and lower independently.
This system offers the following advantages:
- Automatic positioning without manual intervention of the operator (positioning knives on hidden time).
- Cutting without lubrication of the blades, with advantages on the quality of cutting strips.
- Optimal cutting geometry (all the strips come out on the same horizontal axle) for a better slitting quality.
- Can be equipped with 2 heads (for trimming edges) up 8 to 10 heads (for cutting strips of differente widths) without side storage.
Thanks to a modern electronic system combined with an intelligent management software of the positioning and distribution of the individual heads, the automatic positiong slitting head mod. CTBA from BOLLINA is particularly compact because don't require additional space for a sides storage of the not used heads and it automatically performs both the vertical penetration and the correct gap between the blades according to the thickness and kind of the material.
In addition to the traditional slitting lines, this new system finds its ultimate expression in the context of the cut-to-length lines with the integration of the lengthwise cut (Multi-Blanking line) for a significant reduction in size changeover times.
The main features are:
- Standard working width mm 1500 mm.
- Thickness range from 0.5 to 3 mm (2 mm with Uts / Yield 650/320 MPa).
- Working speed up to 70 m/min and cutting tolerances of +/- 0.05 mm.
