Corrugated Tube Crossheads
Multiport spiral-flow design is said to provide a balanced compound distribution with no weld lines to the corrugator.
Guill Tool’s patent-pending extrusion tooling, the Series 400, is said to be adaptable to a wide variety of corrugated equipment and molds.
The tooling features a multiport spiral-flow design that is said to provide a balanced compound distribution with no weld lines to the corrugator. The elimination of weld lines significantly increases the finished product’s overall strength, Guill says.
Models offered include 420, 423, 432 and 434. Features of the 400 Series include spiderless inline, fixed center or adjustable, built-in cartridge heaters, adjustable gum space, low inventory, expandable to multilayer, heated core pin and one-piece body/flow diverter.

Because there are no spider lines, Guill says there’s room for more air and no cold legs. Most products should be run fixed. Users need to change only one component and become fully adjustable. The cartridge heaters are said to offer even heat for better flow and to ensure there aren’t any cold spots. More control of product size is achieved with adjustable gum space. Low inventory results in no burning or stagnation-quick color change.
Due to the fact that it’s expandable to multilayer, the crossheads run a variety of products. Lastly, benefits of the heated core pin and one-piece body/flow diverter are better temperature control and easy cleaning-quick changer, respectively.
