Tech Update
Scrap Choppers are Smooth Operators
Red Bud Industries,
Red Bud, IL, has intro-
duced a scrap chopper
featuring a dual helical
design using a scissor-
type cutting action. This
allows the chopper,
according to company
officials, to operate
more quietly than other
models with a more
controlled and smooth
cutting action. The rotary scrap choppers will only be offered on full Red Bud lines.
The chopper’s knives are attached to a set of rotating drums, driven by an elec- tronic drive. With this design, the rotation of the drums/knives is precisely maintained to create a smooth, scissor-like action to cut the scrap material. This not only reduces sound levels but also minimizes wear and tear on the machine. Each knife features four edges that can be used before the knives must be sharpened. To remove the knives, an operator need only remove one bolt; a locating pin simplifies rein- stalling the knives.
The dual helical scrap choppers are available on Red Bud slitting lines, multiblanking systems and cut-to-length lines with edge-trim systems.

Eifeler-Lafer Variantic Duplex PVD Treatment
Standard Robotic Solutions for Welding, Press Brake Tending
Wolf Robotics, Fort Collins, CO, intro- duces LeanArc pre-engineered robotic- welding cells in a variety of models and with a selection of options available to suit specific application needs. Included are the robot, positioner, torch, human- machine interface, torch cleaner, operator- safety package and welding power sup- ply, as well as a virtual model of the cell for use in optional offline programming. Also optional are remote diagnostics and programming services.
The firm showcased its Lean-Arc cells at Fabtech
last Novem-
ber, and also
displayed its
new assort-
ment of
robotic press-
brake sys-
tems that
offer metal-
formers a
choice of squaring tables, regrip stations, gripper racks (three-gripper capacity), incoming/outgoing pallet stations and quick-change grippers, while also includ- ing safety equipment and virtual-station offline programming.
