US Patent 11427424 Rolled good feeding device and method

The present application relates to rolled good feeding device and method. Material feeding devices and methods are provided for conveying material from material rolls. The material roll may be adjusted in the longitudinal direction during the feeding process by a rectifying frame to aid in maintaining alignment during the unrolling. Tension of the unrolled material may be monitored and unrolling speeds of the feeding device can be adjusted to maintain tension of the material within a range for that material. Aspects also contemplate elements to feed multiple rolled materials simultaneously for subsequent processing in combination as layered materials.
