摘要： An apparatus is disclosed for aligning at least two running webs with each other. It is characterized in that any lateral displacement is corrected at a position at a predetermined distance upstream of the displacement detection point or where excessive tension is not applied to the web to be corrected. Further, correction is made taking into consideration the time for the displacement detectors to follow the web movement and the time for the web to come back to a stable condition after splicing.

摘要： A blank feeder for feeding blanks. It has a feed table on which a plurality of blanks are stacked, a suction unit provided under the table to suck the lowermost one of the stack downward, a motor-driven first feed rolls mounted in the suction unit and adapted to feed the lowermost blank in contact therewith, and second feed rolls located downstream of the first feed rolls and adapted to be driven at a constant speed. The first feed rolls are accelerated from zero speed to the speed of the second feed rolls before the front end of the blank reaches the second rolls, then driven synchronized with the second feed rolls, and decelerated to zero speed again by the time the next cycle begins. A kicker for pushing out the blank may be provided. The kicker is moved forward so as to be synchronized with the second feed rolls before the front end of the blank reaches the second feed rolls. Once synchronized, this state is maintained until the rear end of the blank gets off from the kicker.
