One fusion machine can butt or socket fuse polyolefin pipes and fittings in straight alignment or at inwardly or outwardly mitered universal angles from 0° to 45° for butt fusion and from 0° to 10° for socket fusion. The machine is manually driven, hydraulically monitored and operated in all configurations from one side of the machine.

A pipe processing apparatus, for forming branches on pipes made of thermoplastic material, including a base adapted to be fastened to the outer wall of a pipe and a supporting structure which extends from the base; a support member is slidingly associated with the supporting structure and is adapted to receive an interchangeable processing/handling means configured to interact with the pipe; the apparatus also includes a movement means which engages the support member in order to move it on command along a processing axis. The supporting structure includes a single elongated structural element.

In a packaging machine, a work station has an interior, which is surrounded by a wall and which has arranged therein a tool with at least one heating element or actor. The invention is characterized by a bus node assembly that is attached to the outside of the wall facing away from the interior and which comprises a housing cap, a circuit board and an interface connected to the circuit board and used for connection to a communication bus.

A sealing device for sealing a lid material to sealing areas of a blister web comprises a first, heated sealing tool and a second sealing tool arranged opposite each other and movable relative to each other. A first intermediate element of elastic material is attached to the first sealing tool on a side facing the second sealing tool, and a second intermediate element of thermally-insulating material is attached to the second sealing tool on a side facing the first sealing tool. The first and second sealing tools are movable relative to each other between an opened position and a closed position, in which at least sections of the first intermediate element and of the second intermediate element exert pressure on each other. In the closed sealing position, the first intermediate element rests on the lid material and the second intermediate element rests on lands of the blister web.

A material welder for welding at least two portions of a weldable material together, including: a top bar assembly and a bottom bar assembly, a portion of the top bar assembly directly above a portion of the bottom bar assembly, the top bar assembly including a first and second heating element substantially in the same plane and the bottom bar assembly including a first and second heating element substantially in the same plane, at least one heating device adapted to selectively heat the first heating elements and/or second heating elements, an actuator device adapted to move the top bar assembly towards the bottom bar assembly and/or the bottom bar assembly towards the top bar assembly, such that the first heating element of the top bar assembly aligns with the first heating element of the bottom bar assembly and the second heating element of the top bar assembly aligns with the second heating element of the bottom bar assembly; a contact surface of the top bar assembly and a contact surface of the bottom bar assembly adapted to contact the material during a welding process.

An impulse welding bar (10) for welding plastics films is provided with a detachable non-stick coating (20) which is held on lateral flanks (24) of the impulse welding bar (10). In order to facilitate the replacement of a worn non-stick coating (20), retaining elements (22) are provided which are made of two or more parts and which act in a form-fitting manner in order to detachably fasten the non-stick coating (20) to both flanks (24) of the impulse welding bar (10), wherein first parts (26) of the retaining elements (22) are arranged on the flanks (24) of the impulse welding bar (10) and second parts (36) of the retaining elements (22) are arranged on the non-stick coating (20).

An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and an anvil. The anvil is positionable in close proximity to the horn. Either the horn or the anvil has a face with a width dimension and a circumference and is rotatable about a rotation axis. The face has a raised profile, and a height of the raised profile has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn and the anvil.

A device (1) for delivery of film for a station for packaging by plastic-wrapping, includes: at least two reels (2), each including at least one support shaft (3) for a film roll as well as a film guide (4), in particular in the form of a roller downstream from the shaft; a return roller (5), up to which an unwound film (6) travels from the roll of one of the reels (2); a loader for bringing the reserve film (9) from the roll of the at least one other reel (2) close to the unwound film. The loader includes a rotor (10), which rolls up the reserve film (9) around it in such a way as to bring it close to the unwound film (6). A machine that uses this device as well as a corresponding method are also described.

A welding station for producing a wrapping has a support wheel and a welding device housed on the support wheel and having a head assembly that has a welding member, a support body, and a rod axially movable between a retracted position and a forward position. The support body is integral with an axial end of the rod. The welding device has an abutment assembly having an abutment member and a base assembly engaged to the support wheel. The welding device is configurable in an open configuration where the head assembly and the abutment assembly are mutually spaced, the rod is axially retracted, and the abutment member allows the wrapping to be loaded onto and removed from the head assembly, and a welding configuration where the head assembly and the abutment assembly are mutually engaged, the rod is axially forward and the abutment is engaged by the welding member.

Aspects relate to systems, methods, and apparatus for a manufacturing tool. The manufacturing tool is comprised of a vacuum tool and an ultrasonic welder as a unified manufacturing tool. The manufacturing tool may be used to pick and position a manufacturing part that is then welded with the associated ultrasonic welder.
