The company announces the next generation of this unique and patented tool, The Bullet II. The Bullet II allows quick tooling changes, as the tips remove from the back and the die removes from the front of the unit. The absence of fastening hardware eliminates leaking, as does the taper body and de fl ector design pioneered by Guill. Additionally, the new patent pending CAM LOCK ® de fl ector retaining system offers these additional bene fi ts to extruders and machine builders: • It only takes ½ turn of the Cam Lock ® to remove and install the De fl ector and Tip • No fastening hardware required • Fast tool changes, threaded retaining ring for the die and threaded tip retainer • Dies are removed from the front and tips from the rear • Tooling retainers also provide gum space adjustment • Hassle free air / vacuum connections • Simpli fi ed cleaning • Reduces downtime and lowers operating costs High- and low-volume applications are suitable for this head and are accommodated with the simple, easy changing of just one component. A family of crosshead designs is available and users can specify the “caliber”, that is, the max. die ID. A vacuum chamber and kit for assembly and disassembly are included with the unit. Optional keyed tooling capability of- fers machine designers and end users quick orientation, so the overall unit design enables faster disassembly, proper clean- ing and restart, allowing the line to become more pro fi table, more quickly.
