Dallas Industries delivers feed lines to Lear Seating

May 15, 2017 - Dallas Industries has announced that the Lear Seating facility in Arteaga, Mexico has taken delivery on two feed lines. One line is a 36 in.wide refurbished conventional line featuring model DRF-436 cabinet mounted servo feed, threading table, model DPS-3-36-7 powered straightener and a 20,000 lb. load capacity reel with load car.

The second line is a new 48 in. wide conventional push/pull feed line featuring model DRF-548 cabinet mounted servo feed (push feed), threading table, model DPS-3-48-7 powered straightener and a 20,000 lb. load capacity reel with load car. The pull feed also has a scrap shear integrated for easy scrap chopping. The powered straightener features Dallas’ Hi-Flight back up roll assembly for Advanced High-Strength Steel (AHHS), which is an updated straightener roll backup design that increases roll rigidity over previous designs.  

Both lines were built on an Allen-Bradley, Ethernet-based control architecture and feature SyncLoop and ProfileSelect. SyncLoop controls synchronize the feeder and straightener speeds to dramatically enhance the slack loop’s stability and control. 

ProfileSelect is a unique feed control system that is exclusively available through Dallas Industries. It uses a cam-motion (sinusoidal) profile. This smooth profile results in a feed motion that utilizes 100 percent of the press feed window, reducing stress on the material and the feed’s mechanical components.
