A pressing tool for plastically deforming a workpiece is described. The pressing tool includes a housing and an electric motor for actuating the pressing tool. The pressing tool also includes an instrument seat which is adapted to receive an interchangeable instrument head at the housing. The pressing tool also includes a mechanical safety element which is arranged in a manner that is movable from an open position, in which an instrument head may be inserted into the instrument seat, into a closed position, in which the instrument head is locked in the instrument seat. The pressing tool additionally includes a mechanical actuating element which may interact with the safety element in order to be able to cause the pressing tool to be enabled for a pressing process.

In a method for joining members, a first tube, and a second tube capable of being inserted into the first tube are prepared. The second tube is inserted in a tube hole of the first tube in an axial direction of the first tube. The second tube is radially expanded toward the first tube so that the first tube and the second tube are joined by press-fitting. The first tube is made of a material having a spring back amount larger than a spring back amount of the second tube.

A method for making an air spring assembly, including the steps of providing a bellow, a support ring, and a guide tube. The support ring is positioned relative to a bellow adapter such that a portion of the bellow adapter extends through the support ring. The bellow is then positioned such that a portion of the bellow extends over the support ring and a portion of the bellow adapter. The guide tube is then positioned relative to the bellow and the support ring, such that a portion of the bellow extends into the guide tube and the guide tube is supported by the bellow adapter, and a portion of the guide tube is supported by a ridge support fixture. The first clamp and second clamp are then moved towards the guide tube, applying force to the guide tube, simultaneously forming a first crimp and a second crimp.

A pipe joint device configured to interconnect two pipes to be inserted therein through openings of both opened ends thereof including a joint main body and a joint assembly disposed in the joint main body is provided. The joint main body includes a small-diameter part formed at a central part and large-diameter parts formed at both sides of the small-diameter part. Each of the large-diameter parts has a first horizontal part, a diameter-reduced part of which a diameter gradually decreases from the first horizontal part toward the opening, and a second horizontal part extending horizontally from the diameter-reduced part toward the opening. A portion of each of the second horizontal parts is configured as a curled part inclined toward an outer-diameter direction and the opening of the pipe joint device and then again inclined toward an inner-diameter direction and the opening and having a mountain-shaped section as a whole.

The conceived invention provides both a film applicator and a method for placing a continuous film sleeve around a hose, or a grouping of a plurality of hoses. The sleeve thickness is approximately mil to 20 mils thick, which is suitable for cleanliness protection and reducing the possibility of ripping when the hoses are dragged across a floor. The embodied invention includes a plastic sleeve payout tube, that surrounds and encompasses the hose/hoses. The hoses are routed through the sleeve payout tube when they are hauled into a building to be cleaned. The payout tube stores a compacted length of an enclosing plastic sleeve, and the sleeve pays off as the hoses are dragged into the facility to be cleaned. The initial attachment of the plastic sleeve and hoses is by use of an adhesive tape or an outer clamping strap.
