Automatic apparatus for continuously forming cloth rolls

摘要

An automatic apparatus for continuously forming cloth rolls of a selected length from great size rolls or continuous bands made of a number of cloth pieces sewn together, comprises a detecting means such as a photocell responsive to a seam between two adjoining pieces, positioned upstream of a measuring station which in turn is upstream of a cutting station. Selected advancements of the cloth and corresponding cutting operations are actuated by known automatic devices which are disabled whenever the above-mentioned detecting means senses a seam between two pieces sewn together. Another detecting means such as photocell in correspondence of the measuring station causes the cloth to stop as soon as a seam has reached this position, being preset to this operation by the first-mentioned photocell. With the automatic advancement disabled, the cloth is caused to advance, after the stop, by a fixed length corresponding to the distance between the measuring station and the cutting station. A tube feeding station is also provided for supplying each time a tube being the core of a new roll to be formed, from a tube magazine at a winding station. There are also provided devices for bending the leading edge of the cut cloth around an empty tube, causing this edge to adhere thereon without formation of pleats and discharging finished roll.
