Abstract: In an apparatus in which cylindrical articles violently collide with one another as they roll down on the inclined skid rails, from the inlet to the outlet thereof, a control rail covered thick with a soft and elastic foamed substance is located. The control rail is positioned side by side in parallel to the skid rails, and frequently reciprocated vertically to brake the articles as they move downwards over the skid rails so that the maximum rolling speed is sufficiently reduced for restricting the noise of collision below an allowable level.

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.
