An automatic welding machine, comprising a supporting frame and a tensioning device for reversibly joining at least two opposing booms to one another and applying a tension force between these, having an open position in which the opposing booms are separated from one another by a gap and a closed position in which the opposing booms are joined to one another and braced with respect to one another. One boom is mounted in a torsion-proof manner on the tensioning device and is pivotable in relation to the other boom and can be moved out of the open position into the closed position by the pivoting of the tensioning device. The tension force is generated by way of a spring-loaded element disposed on the tensioning device, wherein the spring-loaded element, at one end, is rigidly connected to a supporting element of the tensioning device and, at the other end, is pivotably mounted on the supporting frame by way of a double swivel joint, and the spring-loaded element is tensioned by the pivoting of the double swivel joint out of the open position into the closed position, whereby a torque is applied onto the pivotable boom.

An automatic welding machine for lap welding the edges of plastic webs, comprising a movable supporting frame, a heating device for partially melting the plastic webs, at least two opposing, counter-rotating pressing rollers and/or advancing rollers, at least one of which being driven, and at least one driving device comprising a drive motor and at least one gearbox for driving the pressing and/or advancing rollers, wherein the pressing rollers and/or advancing rollers are driven by the driving device by way of at least one flexible shaft. Furthermore, the gearbox can be implemented as a worm gear mechanism comprising a worm that is seated directly on a motor shaft of the drive motor and two counter-rotating worm gears driven by the worm.

An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.

A tool for applying tint film to an inside window surface of an automobile has a unitary body with a handle portion and a downwardly depending neck extending from the handle portion to an elongate blade supporting portion. The blade supporting portion includes a bottom zone extending to a chamfered distal end. A flexible blade is attached to the bottom zone and the distal end of the blade supporting portion. The flexible blade includes a forwardmost portion that extends beyond the distal end of the blade supporting portion.

A double ended hand tool created to pick up place and position flatback crystals, gems or other tiny items is disclosed. The tool contains a hollow, conical end which securely encases each crystal allowing the operator to easily position the crystal with no slip. The tool has a first end and a second end coupled by a shaft. The first end has a wax tip which allows the user to pick up crystals or other small items. The second end has a hollow narrow extended portion which allows the users to manipulate the crystal or other small items.
