Dallas Industries Delivers Feed Line to ITW Drawform

Dallas Industries, a manufacturer of coil-handling, press-feeding equipment and controls for the stamping industry, has delivered a new conventional feed line to ITW Drawform, Zeeland, MI, a contract manufacturer of deep-drawn metal stampings. The line, designed to feed lighter-gauge material, has provisions to avoid marking cosmetic materials. It can handle coil widths to 30 in. with a sheet thickness to 0.050 in. at full width, and is rated for handling coil weights up to 20,000 lb.

Included with the line: a coil reel with load car that includes a coil restrictor (holddown) and automated coil guide rolls that automatically center the coil on the reel. Additionally, the reel features a dual brake system, including an Eaton AirFlex brake ideal for use with thin, sensitive materials. An automatically adjusting proportional valve adjusts brake pressure based on coil OD. The line also includes a DPS-2.25-7-30 powered straightener with non-marking provisions for soft and/or cosmetic material, and a DRFP-330 servo roll feed mounted on an adjustable-height cabinet.

Dallas’ SyncLoop technology monitors slack-loop depths and adjusts payout speed based on the line speed average from the feeder. The feed also includes triple-roll (per side) hand-crank-adjusted edge guides with self-centering and independent adjustments for squaring of soft and light gauge materials. 

The line is built on an Allen-Bradley Ethernet-based control architecture and features ProfileSelect, a unique feed control system exclusively available through Dallas. It uses a cam-motion (sinusoidal) smooth profile that results in a feed motion utilizing 100 percent of the press feed window, reducing stress on the material and the feed’s mechanical components.
