A method and a device for obtaining a joint between two surfaces of two parts that have a simple curvature are proposed in which a mandrel is placed below the first surface, which contains a moving stamp in its interior. A template is placed above the second surface, which has a deep drawing opening. The stamp is moved along the surface normals of the two surfaces, such that material forming the two surfaces is forced into the deep drawing opening, wherein the deep drawn and compressed portion of the first surface engages behind the remaining part of the second surface to obtain a form-fit connection between the two surfaces. The stamp blocks a channel inside the mandrel until pressure from a medium therein causes the stamp to move.

An apparatus for forming and sealing a duct member for use in an air handling system. At least one work station accommodates a work piece, which is generally a cylindrical tube.

A pressing tool includes a housing and pressing jaws arranged outside the housing. One or both pressing jaws can be pivoted into the open position by a user's hand acting upon the respective pressing jaw that faces the housing. An actuating switch is formed on a pin-like holding projection having a longitudinal extent with a free end which protrudes from the housing at an acute or right angle. A dimension of the holding projection transverse to the longitudinal extent is smaller than a smallest diameter of the hand region.

A coupler for coupling together a lead pile segment and an extension pile segment of a driven pile comprises: a cylindrical pipe segment, having first and second formed ends and a cylindrical body extending therebetween, each of the first and second formed ends having an inner diameter that is greater than an inner diameter of the cylindrical body. The first formed end is sized to snugly receive an end of the lead pile segment and the second formed end is sized to snugly receive an end of the extension pile segment. Each of the first and second formed ends has an initial length. When an axial force is applied to the extension pile segment, each of the first and second formed ends undergo secondary end forming to thereby achieve a final length of each formed end, wherein the final length exceeds the initial length of each formed end.

A forming assembly for forming a wick is disclosed. The forming assembly includes a tube inflatable to an inflated configuration. A wick mesh is configured to be wrapped about the tube. The forming assembly further includes a sheath positionable about the tube and the wick mesh. The tube and the sheath are configured to compress the wick mesh and form the wick based on the tube inflating towards the inflated configuration.

Power tool, in particular a pipe press, including a drive, an output shaft, a threaded spindle drive and a linear actuator, wherein a torque generated by the drive is transmissible via the output shaft, and the threaded spindle drive connected to the output shaft, to the linear actuator. The power tool includes an eccentric transmission device for a torque adaptation between the drive and the threaded spindle drive, wherein the eccentric transmission device includes a drive eccentric, which is drivable by the drive, an eccentric gear, which is drivable by the drive eccentric, and a compensating coupling, which is drivable by the eccentric gear and which serves for transmitting torque from the eccentric gear to the output shaft.

A collar for applying a radial compressive force to an outer surface of a tube and a tube assembly including the collar and the tube.
