Measuring, cutting and rolling apparatus
摘要:
An apparatus is provided for measuring, cutting, and rolling material such as floor covering. The apparatus includes a wheeled support frame which receives a base roll of material from which material is unwound a material take-up shaft device onto which material from the base roll is wound. The take-up shaft device includes a pair of outwardly expandable bars which clamp the edge of the material in place on the take-up device and which can be contracted to release the old material from the take-up device. The take-up device is releasably mounted on the support frame by a mechanism which permits the entire take-up device with a roll of material wound thereon to be removed from the remainder of the apparatus. A measuring device measures the length of the material wound onto the take-up device and a floating cutting table assembly including a cutting bar assists in cutting off the material from the base roll when the material wound onto the take-up device is of the desired length.
