Extrusion International 3-2021

22 Extrusion International 3/2021 INDUSTRY NEWS however this cross- head de- sign can also be adapted to fi t any extruder design or line layout. The addition of a newly designed fl ow inlet channel reduces the shear and heat that is generated as the materials are be- ing processed. This leads to lower head pressures allowing the material to move through the head in a much more bal- anced and even fl ow. All crossheads supplied by Guill are furnished with a tool kit for assembly and disassembly as well as a detailed operator’s instruction manual. The engineering team at Guill will gladly assist users in the implementation and operation of the NEW 500 series crosshead.

The ex- pansion will propel the site to become a regional hub for best-in-class tacki fi er and reinforcing resin production and technology. The investment, slated for completion later this year, ad- dresses an increasing demand for Novolac tacki fi ers in one of our core regions. “We have taken the decision to further grow capacity as another step forward in reinventing our business model,” stated Robert Kaiser, Vice President, Rub- ber & Adhesives Solutions at SI Group, adding, “This expan- SI Group www.siigroup.com sion will not only bene fi t the region’s supply, but will provide superior solutions at the highest reliability of supply to all our customers globally.” SI Group has a long history of manufacturing tacki fi er res- ins used to enhance the performance and durability of tires. In addition to tacki fi er resins, the company also has a robust portfolio of antidegradants, bonding, curing, and reinforc- ing resins, manufactured globally. This expansion follows the company’s announcement in September 2020 to also expand resin capacity in Nanjing, China. „ Guill Tool introduces theNEW500Series crossheadwithMAGS gum space adjustment. The 500 Series is designed speci fi cally for the fl ow characteristics and unique processing challenges of elastomeric compounds. One of the key features engineered by Guill on this new crosshead design is the mechanically assisted gum space (MAGS) adjustment system. This new method of gum space adjustment allows the operator to make an effort- less adjustment from a single point using a common socket wrench. No more need to struggle with multiple nuts and bolts in order to adjust gum space, which leads to faster adjustments. The visual indicator on the core tube allows the operator to see how far the gum space has been moved, making those adjust- ments muchmore accurate and repeatable. The hardware-free and patented cam lock design of the NEW 500 Series from Guill means no time is wasted unbolting and re-securing fasteners for disassembly and re-assembly. Only half of a rotation of the cam nut is required to loosen and au- tomatically extract the de fl ector from the head body, which is another time saver. Also, with no undercuts on the de fl ector, there are no material hang-ups when extracting the de fl ec- tor, allowing for faster and easier cleaning and changeover. The NEW 500 Series also features the latest Center-Stage concentricity adjustment system that signi fi cantly reduces pressure on the tooling, allowing easier and more precise concentricity adjustments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow simple re- placement of locked or damaged adjusting bolts, which fur- ther saves on repair and downtime. Another innovative feature of this new rubber/silicone cross- head is a cast aluminum liquid-fed cooling sleeve that allows the user to switch out the cooling jacket in the event of a line obstruction, again reducing downtime compared to tra- ditional integrated cooling systems. The NEW 500 Series crosshead with MAGS gum space adjust- ment is a drop-in replacement on most existing NRM lines, Guill Series 500 crosshead with Mechanically Assisted Gum Space (MAGS) adjustment…specially designed for the fl ow characteristics of elastomeric compounds
