摘要： A machine for spirally forming pipes that is readily transportable to various locations. The machine is mounted to the surface of a conventional tractor-trailer arrangement and includes an uncoiler assembly with a structural extension arrangement for transferring coils from delivery vehicles. The uncoiler assembly is pivotably mounted to allow for rotational travel to meet with coil delivery vehicles. Sheet material is uncoiled and fed to the spiral forming assembly by an assembly of cylindrical rollers with rotational energy provided by internal combustion engine. The spiral forming assembly is pivotably mounted with motorized connection and programmable control for helix angle and third set of rollers adjustment. The spiral forming assembly and the assembly of cylindrical rollers are mounted with bases of minimal height for stability. An internal combustion engine driven cut off assembly is mounted directly to the spiral forming assembly to cut off pipes as they are produced. The machine has multiple pipe support stands that may be stored on the tractor-trailer arrangement with the pipe machine, and quickly set up at various locations.

摘要： A pipe arching apparatus, comprising an internal means for flattening and elongating the lower circumference of a pipe, while said pipe is positioned upon the ground. The apparatus is retractably compactible to be towably transportable and will arch pipes of larger size and longer lengths than traditional pipe arching equipment. It is powered by an internal combustion engine, has hydraulically extendible radius forms for forcibly reshaping the inside of a pipe, and is steerably drivable into and out of a pipe.
