Fibreglass reinforcements for adhesive tapes
For over 30 years, Gavazzi has produced fibreglass reinforcements for adhesive tapes, working with the world’s leading tape manufacturers. Founded in 1881, the Company is based in Northern Italy with its headquarters in Calolziocorte (LC) and 2 other production plants near Milano and Bergamo.

Recently Gavazzi has modernised and expanded its dedicated production division to meet the demands of an increasingly varied and quality-oriented market. A third generation lamination line (4.0) has been installed, together with a creel equipped with a sensor system which automatically detects yarn breaks and stops the line instantly.

The reinforcements for adhesive tapes can be unidirectional—also called uniaxial—or bidirectional, meaning they are woven into a lightweight fabric.

When unidirectional reinforcements are used, fibreglass yarns are laminated onto a film supplied by the customer with a thin adhesive coating. Yarn count and thread density will vary depending on the strength of the reinforcement (N/cm) requested by the customer.

When bidirectional reinforcements are required, Gavazzi offers a full range of lightweight fabrics of varying grammage and geometry. Fabric can be either laminated onto pre-coated film supplied by customers, or the company can supply fabric in jumbo rolls if lamination is carried out by customers in their facilities.

Polyester reinforcements for duct tape
Since 2001, Gavazzi has been developing and producing at their Cisano Bergamasco (BG) plant lightweight polyester fabrics for the reinforcement of duct adhesive tapes. These fabrics are manufactured using German knitting machines which can work with great precision and reliability at widths of over 5 metres.
