  • a known example of a decoiling device to decoil a large steel coil for feeding the steel into a roll-forming machine or the like, hereinafter referred to as a forming machine is an expanding mandrel type decoiling device.
  • a coil of feed material slides over a mandrel that expands to contact the inner diameter of the coil.
  • the coil is supported by the mandrel, which includes a rotating shaft that supports the weight of the coil, so that the coil of material is unrolled or decoiled, and then fed into a roll-forming machine.
  • Other devices such as a drum type decoiler are known, wherein the coiled feed material slides on a drum and is then fed into a roll-forming machine.
  • Telescoping is the result of inner layers of the coiled material shifting axially slightly off center, so that one end of a layer extends beyond an end of the coil, while the opposite end of that layer recedes inside the coil.
  • the stress produced by a single telescoped layer applies a similar axial displacing force on the adjacent layer, and the effect cascades through the layers producing the telescoping phenomenon.
  • the steel coil becomes telescoped in a manner such that the axis of the coil is so skewed from the axis of the inner telescoped layers, that the coil is functionally detached from the inner most layers. At this point the skew in the layers of the coil can render the coil unusable. The operator then must manually straighten the coils out before they can be fed into a roll-forming machine.

Abstract

La présente invention concerne un dispositif de déroulage destiné à dérouler un rouleau de matériau en feuille comprenant un premier et un second galet de support sur lesquels repose le rouleau. Le premier et le second galet de support sont orientés de sorte que leurs axes de rotation soient parallèles à une première direction. Le dispositif de déroulage comprend également un cadre soutenant les deux galets de support, un mandrin rotatif et un premier et un second élément de guidage. Le premier et le second élément de guidage sont positionnables sur un premier et un second côté du cadre, respectivement, pour limiter le déplacement du rouleau de matériau en feuille dans la première direction. Il est possible de configurer plusieurs dispositifs de déroulage de ce type avec un élément de support soutenant ces différents dispositifs pour obtenir un système de déroulage multi-rouleau mobile qui est transportable d’un emplacement à un autre.
