Carell introduces new 305HV angle rolling machine

Laser welded profiles

ASPECIAL line from PM sas, Italy, combines the advantages of the roll forming process with the precision of a laser welding unit. The line allows the production of a wide variety of products, such as automotive profiles, electrical cabinets, buildings, perforated pipes, windows and door profiles. This solution is composed of three parts: punching and notching press (so it is not necessary to work the piece twice); roll forming line (precision, flexibility and long production life); and laser welding unit for high precision and welding without smears. With PM’s interchangeable cassette system, the forming rolls of a profile can be changed for another in a very short time, while the punching system is flexible and can be changed from the PLC.

CARELL Corporation has introduced the new 305HV (shown with optional CNC control panel) to its angle rolling machine line up. The Carell 305HV is a three roll, double initial pinch universal bending machine with independent hydraulic adjustment of both lateral bending rolls and powered rotation of all three bending rolls. These versatile units are ideal for rolling standard/ special sections plus tube/pipe in mild- structural-stainless steels, aluminium, brass, copper as well as other materials. Machines are furnished with a set of standard universal rolls. The  305HV includes dual LED

material types, tri-directional lateral guides with cam rollers for correcting inherent twist when rolling angle leg-in, and it operates in both horizontal and vertical positions. Carell Corporation – USA Fax: +1 251 937 0957 Website: www.carellcorp.com

digital displays to monitor bending roll positions, double pinch geometry which permits pre-bending of leading and trailing ends of the profile without removal from the machine, telescoping modular multi-component roll set specifically designed to bend standard sections including angle leg-in/out and square rectangular tube as well as other shapes in a variety of

Roll-Kraft sponsors roll forming workshop

1. Complete slitter line with following specification: ■ Max. coil weight: 36 ton ■ Coil width:

ROLL-KRAFT recently participated as the industry sponsor of the Fabricators and Manufacturers Association (FMA) world- class roll forming workshop. Attendees were urged to bring along their questions, drawings, and roll formed parts to the workshop to get answers to problems they were experiencing. Topics included presentations of basic and more complex roll form systems, metallurgy as it applies to roll forming, tooling installation, use of high strength steels, basic machine applications, lubricants, troubleshooting, and many other subjects. Gary Summerhill, engineering manager of Roll-Kraft, conducted a class entitled Roll Forming High Strength Steels – A Design Perspective. This class covered the many options of using high-strength steels, including when they are preferred, and a comparison to other commercial

grade steels. There was an overview of tooling materials, tooling life, lubrication, equipment, and general information on the advantages and disadvantages of using the various steels. Roll-Kraft provides tooling, and equipment to the tube and pipe and roll forming industry. Participation and reliance on the well-earned ISO 9001:2000 quality management certification programme has helped customers in more than 50 countries identify Roll-Kraft as a reliable source of high quality products and programmes. Roll-Kraft also provides a full spectrum of services to roll forming and tube & pipe manufacturers including the design of tooling using FEACopra software to identify problem areas before manufacturing begins.
