An unscrambler for unscrambling a bundle of elongated tubes comprises a plurality of forward belt- support columns, a plurality of aft support columns, a plurality of flexible belts suspended in parallel between the forward and aft support columns forming a belt magazine for retaining the bundle of tubing which extend longitudinally in a direction perpendicular to the belts, and a plurality of ramps positioned longitudinally between each pair of adjacent belts sloping upwardly towards the forward support columns and positioned such that they provide support for the bundle in the belt magazine. The ramps each have a wedge extending from their upper surfaces, and each wedge has a forward face which intersects the upper surface of the ramp to form a v-shaped groove on the ramp. Furthermore, each of the belts have a cleat attached to their upper surfaces. Tightening of the belts causes the bundle to be guided up the ramps and lifted above the wedges on the ramps such that the bundle expands outwardly. Subsequent slackening of the belts causes the expanded bundle to be lowered onto the wedges such that the wedges separate a portion of the tubes from the bundle and such that the v-shaped grooves retain the separated portion of tubes on the ramps. Tightening of the belts again causes the cleats to engage and convey the separated tubes from the ramps to a magazine ramp adjacent the forward support column.

ppareil servant à défaire un paquet de tubes ovalisés comprenant une pluralité de colonnes de courroies de support avant, une pluralité de colonnes de support arrière, une pluralité de courroies flexibles suspendues en parallèle entre les colonnes de support avant et arrière formant un magasin à courroie pour retenir le paquet de tubes qui se prolongent longitudinalement entre chaque paire de courroies adjacentes en pente ascendante vers les colonnes de support avant et positionnées de manière à supporter le paquet dans le magasin à courroie. Les rampes comportent chacune un coin se prolongeant à partir de leurs surfaces supérieures, et chaque coin présente une surface avant qui rencontre la surface supérieure de la rampe pour former une rainure en V sur la rampe. De plus, chaque courroie comporte une agrafe fixée à sa surface supérieure. Le serrage des courroies provoque le guidage du paquet vers le haut des rampes, son soulèvement au-dessus des coins, sur les rampes, de manière telle que le paquet se déploie vers l'extérieur. Un déserrage subséquent des courroies fait descendre la paquet sur les coins, qui ont pour effet de séparer une partie du paquet de tubes, les rainures en V retenant sur les rampes les tubes ainsi séparés. Le reserrage des courroies provoque l'accrochage des agrafes sur les tubes et le déplacement de ces derniers, des rampes à une rampe magasin, à côté de la colonne de support avant.
