Two Press-Feed Lines for Lear Seating in Mexico

Monday, May 15, 2017

Dallas Industries, Troy, MI, has delivered two feed lines to the Lear Seating facility in Arteaga, Mexico. One, a 36-in.-wide refurbished line, features a DRF-436 cabinet-mounted servo feed, threading table, DPS-3-36-7 powered straightener and a 20,000-lb.-capacity reel with load car. The second is a new 48-in.-wide conventional push/pull feed line featuring a DRF-548 cabinet-mounted servo feed (push feed), threading table, DPS-3-48-7 powered straightener and a 20,000-lb.-capacity reel with load car. The pull feed also has a integrated scrap shear for simple scrap chopping. The powered straightener features Dallas’ Hi-Flight backup-roll assembly for advanced high-strength steel.

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