  "description_excerpt": "The present invention relates to a chute for a cement truck and a method of fabricating a chute for a cement truck. In particular, the present invention relates to a chute for a cement truck fabricated from UHMWPe.\n\nThe prior art reveals cement truck chutes manufactured from steel and aluminium. One drawback of such prior art chutes is that due to the corrosive and abrasive nature of the cement the chutes become quickly worn and must be replaced. In order address this drawback the prior art discloses providing a liner covering the metal chute and made of a material which is better able to withstand the abrasive cement such as UHMWPe. These liners have the drawback that they are typically riveted to the chute and therefore quickly become dislodged thereby exposing the metal chute.\n\nIn order to address the drawbacks of the prior art, there is disclosed a chute assembly for directing cement from a cement truck. The assembly comprises an elongate chute of generally u-shaped cross section fabricated from UHMWPe and comprising an upper end and a lower end, a plurality of reinforcing rods arranged along a length of and encased within the UHMWPe, one end of each of the rods adjacent the upper end and another end of each of the rods adjacent the lower end, a pair of u-shaped collars, an upper one of the collars adjacent the upper end and a lower one of the collars adjacent the lower end, and a fastener for securing each of the collars to their respective rod ends. There is also disclosed a method for fabricating a chute for directing cement from a cement truck.",
