    Abstract: The apparatus employs a stationary supporting structure for mounting a curved mandrel, to provide a platform for a truck to ride thereon, and to provide a cam slot in the platform which corresponds to the curvature of the mandrel. The truck has a rotatable winding head on its upper side and a cam follower extending from its underside positioned in the cam slot. When movement is imparted to the truck, the cam follower traverses the cam slot and the winding head traverses the mandrel to wind material onto the mandrel.

    Abstract: A METHOD AND APPARATUS IS PROVIDED FOR CONTINUOUSLY MAKING FIBER REINFORCED PLASTIC PIPE IN WHICH A CONVEYOR TUBE IS FORMED ON AN AXIALLY FIXED HOLLOW ROTATABLE MANDREL. A PLURALITY OF BANKS OF RESIN IMPREGNATED FIBER ELEMENTS ARE WOUND ON THE CONVEYOR TUBE AS IT ADVANCES TO PROVIDE THE PIPE ASSEMBLY. THE TERMINAL END OF THE GENERATED PIPE ASSEMBLY IS SEALED WITH A PLUG. A FLUID UNDER

    PRESSURE IS FED THROUGH THE HOLLOW MANDREL AND OUT THE FORWARD END OF THE MANDREL INTO A CHAMBER FORMED BY THE GENERATED PIPE ASSEMBLY, THE PLUG, AND A FLUID SEALING MEANS WITHIN THE PIPE ASSEMBLY BEING GENERATED, THEREBY CAUSING THE PIPE ASSEMBLY TO ADVANCE.

    Abstract: A pipe coupling device is provided which comprises a pair of parallel, telescopically arranged frames. Each frame is provided with means for holding or clamping a pipe section. The frames are connected to one another by tension springs. Manually operable means is employed to place the springs in tension so that the joint provided by the mating ends of pipe sections coated with a cement has constant, resilient pressure applied thereto.

    Abstract translation: 提供一种管连接装置,其包括一对平行的可伸缩布置的框架。 每个框架设置有用于保持或夹紧管道部分的装置。 框架通过拉伸弹簧相互连接。 使用手动操作的装置来将弹簧放置在张力中,使得由涂覆有水泥的管段的配合端提供的接头具有恒定的弹性压力。
