Mechanical Roll Feeder RF-NS Series for Press Lines | Yiming, Dongguan, China

Yiming's Mechanical Roll Feeder RF-NS Series feeds metal strip into a press in precise steps. It is built for high-speed precision stamping lines and is offered in feeding widths from 100 mm to 500 mm.

The feeder is driven by the press output shaft, so it needs no separate electricity or gas supply. It is recommended where the press runs above 200 strokes per minute (SPM). A typical line pairs it with an uncoiler, the press and an automatic winding machine.

Key Features

• Driven mechanically from the press output shaft, with no electrical or gas supply needed
• Feeding length is set by adjusting the feeder to match the die, whatever the material width or thickness
• Feeding accuracy of ±0.05 mm, improving to ±0.01 mm when guide pins are used for positioning
• Telescopic adjustable pull rod and rocker arm set to standard transmission angle for safe use
• Quiet running
• Runs continuously and is easy to operate
• Suited to a line of uncoiler, strip feeder, press and automatic winding machine
