Claims

[Scope of utility model registration request]

In a feed roll device that is equipped with a pair of rolls that rotate and repeatedly clamp and release, and in which a coil material is inserted between these rolls, one roll of the pair of rolls clamps this roll with respect to the other roll. , an air cylinder to be released is connected, this air cylinder is provided with a clamp air chamber and a release air chamber separated by a piston, and a first regulator connected to an air source is connected to the clamp air chamber, and a quick exhaust valve is connected to the air cylinder. and a second regulator connected to an air source to the clamping air chamber is connected to the clamping air chamber via a switching valve and the quick exhaust valve, and a check valve is provided between the switching valve and the releasing air chamber. and a throttle valve in parallel, the switching valve connects the second regulator and the clamp air chamber via the quick exhaust valve, and the release air chamber is opened to the atmosphere via the check valve. and a second switching position where the second regulator and the release air chamber are connected via the throttle valve and the clamp air chamber is opened to the atmosphere via the quick exhaust valve. A release amount setting device for a feed roll device, characterized in that:
