A strip process line has a high back coil car for automatically banding coil of metal strip on the coil car. The process line runs while banding occurs on the coil car. The coil car includes an outer frame, and coil receiving saddle with a pair of blocker rolls or a V saddle, and a hold down arm and a plurality of strap guide channels. By the high back car being docked with an automatic loading station, the process line can run while the banding takes place on the coil car, and keeps the operator safely away from the coil car until the banding is completed.

An accompanying squeezing unit in a machine for winding plastic film onto bobbins, in which at least two spindles are positioned on a rotating plate around a central shaft constrained to an upright of the machine, the group including an accompanying squeezing roll situated on a lever mechanism which is selectively actuated to rotate-oscillate by actuators in order to maintain the squeezing roll positioned on a film in the final winding onto a bobbin positioned on one of the spindles, the lever mechanism being activated when the plate carrying the spindles is rotated to discharge a finished bobbin. The lever mechanism in the group includes two first levers and two second levers articulated relative to each other.

A multifunctional apparatus of automatic punching, laminating, tape-preparing and cutting for a tailing end of a coiled material and a method associated therewith are provided. The apparatus is provided with a winding device and the coiled material. The coiled material is wound on a rotating shaft of the winding device. A robotic arm is disposed above the winding device. One end of the robotic arm is mounted with a punching, tape-preparing and cutting mechanism, and the other end thereof is rotatably connected to a centering and deviating-correcting mechanism fixed on a winding diameter tracking mechanism. The robotic arm is driven by a motor or a pneumatic cylinder or a hydraulic cylinder. The winding diameter tracking mechanism is slidably disposed on a rail of a rack. The apparatus and method can improve efficiencies of winding and jointing of coiled materials, and reduce production cost.

A method for fixing a tail end of a toilet paper roll and the toilet paper roll therefrom. The end of the toilet paper roll is not adhered with glue, but the circumference of the toilet paper roll is wrapped by a paper sheet except the toilet paper roll. The head and the tail ends of the paper sheet are not adhered with glue, but joined together in a mechanical combination way, so that the tail end of the toilet paper roll is hooped onto the paper roll by the paper sheet. In this way, there is no need to apply a pressure or any other treatments between the tail end and the external layer of the paper roll when fixing the tail end of the paper roll, the damage of the external layer of the paper roll is avoided, and the quality of the finished paper roll is improved.
