A weld wheel cleaning system is provided to clean or remove a layer of embedded material and other debris produced from welding from the working surface of a weld wheel. Such a weld wheel cleaning system includes a cleaner with an abrasive material positioned on an outer surface of the cleaner. The cleaner is positionable adjacent to the weld wheel such that the abrasive material is aligned with the working surface of the weld wheel. An actuator can be used to selectively actuate the cleaner with a force sufficient to remove the layer of embedded material from the working surface of the weld wheel with the abrasive material. The debris from the cleaner can be removed by a vacuum.

A plastic welder comprising a control unit comprising a bulkhead assembly, a torch assembly comprising a torch hybrid connector, and a hybrid cable hose assembly comprising a hybrid cable hose including a threaded portion, a first overmolded portion, a second overmolded portion, wherein the torch assembly is removably attachable to the bulkhead assembly of the control unit by the hybrid cable hose assembly.

An apparatus for fabricating an elastic nonwoven material generally includes a first bonding module and a second bonding module. The second bonding module is positionable in close proximity to the first bonding module. At least one of the first bonding module and the second bonding module has a face with a width dimension and a circumferential axis and is rotatable about a rotation axis. The face has a plurality of ridges. The ridges are positioned such that at least two adjacent ridges overlap along the circumferential axis.

A longitudinal sealer includes a housing, an arm, and a heating element. The housing is configured to be installed in a foam-in-bag system. The arm is movably coupled to the housing. The heating element has a leading edge exposed through an exterior surface of the arm. A position of the arm with respect to the housing is controllable so that the arm is movable between a first location where the leading edge of the heating element is not in contact with a film in a film path of the foam-in-bag system and a second location where the leading edge of the heating element is in contact with the film in the film path of the foam-in-bag system.

A packaging machine comprising a machine frame and at least one workstation with a lifting gear for supporting and moving a lower tool part between an open and a closed position. The workstation may include an upper tool part to act in cooperation with the lower tool part during a working operation. The lower tool part may be engaged with or near in proximity to an upper tool part in the closed position, and will be spaced apart from the upper tool part in the open position. A tilting mechanism is provided for a tool changing operation to tilt the lower tool part into a tilted position when the lower tool part is in the open position. In one embodiment, the lower tool part is removed from the packaging machine on a rail system in the direction corresponding to the tilted position.

A method for operating a packaging machine comprising a work station with an exchangeable tool. A control device may be integrated into the tool. When the tool is in a state of the tool installed into the work station, the control device may regulate a temperature of the tool based on an operating temperature target specification by suitably supplying a heating device integrated into the tool with electrical power. Further, when the tool is in a state removed from the work station, the tool may be connected to an external power supply, and the control device may regulate the temperature of the tool based on a preheating temperature target specification by suitably supplying the heating device with electrical power provided by the external power supply.
