Understanding Coil Handling/Press Feeding Operations
A primer for non-technical personnel
In the past ten years or more, a major technological change has taken place in the feeding method of presses. For example, achieving higher processing speeds, flexibility, better quality, reliability, etc.
The press feed only moves the right amount of material into the tool, but it also is positioned correctly in the mold—from front to back, from side to side, and at right angles to the tool.
Basic Coil Handling Principles
- The feed settings must be flexible enough to adapt to the various applications on the production line.
- The feed must deliver the material into the tool with sufficient accuracy.
- The feed should deliver the material appropriately to keep up with the line speed.
Coil Feeder Types
The two basic feed types are roll feeds (press drive and servo drive), and gripper feeds.
The press can power roll feeds (usually considered older technology or for high-speed, dedicated press applications) or their own independent drive system (most applications today). And HE is mainly involved in the latter servo drive solution.
