fences offer a combination of durability, flexibility and safety. With more than 90 years’ experience designing and building fence-related machinery, Bergandi Machinery has in excess of 2,500 machines in operation in more than 65 countries around the world. Along with its flagship chain link weavers, the company produces high speed (Iowa-style) continuous-twist barbed wire machines; high-tensile reverse-twist barbed wire machines; PVC extruders for use in the manufacture of colour chain link; fuse-bonded systems to produce thermally fused organic coated wire for chain link; concertina/ razor wire systems; and other related equipment. Bergandi also offers a full line of parts, and training for operators, either at their own location or at the company’s headquarters in Ontario, California, USA.

Low-volume adjustable-centre co-extrusion crosshead for PVC over PVC

Additional features of the crosshead include multi-port spiral flow, easy disassembly and restart, positive seals for leak elimination, the patented Guill Feather Touch concentricity adjustment, a vacuum port and the ability to accept two extruders from the same side via the heated manifold assembly. The crosshead is adaptable to all extruder brands. It has a maximum through-core of 1.75" and a maximum die ID of 2". The first layer is fixed and the second is adjustable. A tool kit and detailed operator’s instruction manual are supplied. Guill is an extrusion tooling designer and manufacturer with nearly 60 years of experience. Its engineers specialise in plastic extrusion tooling design, utilising advanced technology and drawing on years of experience to tailor tooling

Guill Tool’s Series 725 co-extrusion crosshead for tray cable applications, constructed from stainless steel, offers machine builders and end users advantages that include the patented Seal Right system of self-aligning tapered deflector and body design. Series 725 was developed by Guill in partnership with a customer, to convert a production line from a tandem line with two heads a distance apart into a co-extrusion line with a single head applying both layers of PVC in a single operation. Other end-user benefits of the co-extru sion crosshead include a shorter change over time; less scrap with a single head set-up; improved product quality from the increased adhesion between lay ers, as melt adheres to melt rather than extrudate; and an inner layer that is not exposed to the environment (which can allow contaminants between the layers).

and die design for the industry, helping to increase efficiency when operating plastic extruders. The company’s products can assist operations from the extrusion of PVC pipe to complex profile co-extrusion.
