  • Apparatus collecting pipes and the like
    Patent number: 4147260
    Abstract: An apparatus which collects pipes, rods and similar objects parallel one another, to form a bundle. The apparatus includes at least one pair of transfer rails from which the pipes are transferred to a pair of roller chains where the pipes are collected. The roller chains are mounted on driving sprockets, swing sprockets, feed sprockets and take-up sprockets. The velocity of the take-up sprockets is lower than the velocity of the feed sprockets, causing the roller chain to sag therebetween, creating a space to collect the pipes.
