Abstract: The invention relates to a method for assembling a roller conveyor having rollers for products, each having a cylindrical roller body and a first and second support element on opposite ends of the roller body, the second support element having pulley means; providing a frame having a first and second frame part for mounting therebetween the rollers; and, for the purpose of mounting a roller to the frame: mounting the first support element to a first mounting provision of the first frame part; passing a drive element and a further drive element over the pulley means of the roller; tensioning the drive element by exerting a force on the roller by means of a tensioning device; mounting the second support element of the roller to a second mounting provision of the second frame part while keeping the drive element tensioned; and removing the tensioning device from the roller.

Abstract: A quick-release buckle for a shoulder strap and preventing unintentional release when tension exerted by the shoulder strap. The buckle includes a socket member, a plug member, and a locking member. The plug member has the shoulder strap connected thereto, and is replaceably engaged with the socket member. The locking member is an operative part of the socket member. The plug member replaceably engages in the locking member in such a manner so to be released therefrom, the locking member is released and the plug member has to be pulled in a direction opposite to that in which tension from the shoulder strap is exerted so as to prevent the unintentional release of the quick-release buckle when the tension is exerted by shoulder strap, while the tension exerted by the shoulder strap when the plug member is engaged in the locking member assures unintentional release of the quick-release buckle.
