The invention relates to a wire-feed device for conveying a wire and to a method for feeding wire using a wire-feed device, in particular for a thermal joining apparatus, having at least one a drive element which can be operated by a feed drive and can be placed against a wire guided through the wire-feed device, exerting a contact pressure, in order to transfer drive movement by friction. According to the invention, an actuator which is coupled to the at least one drive element and can be controlled by a controller using the values measured for the contact pressure, is provided for variably setting the contact pressure acting on the wire.

A strap feeding device includes first driving and driven rollers, second driving and driven rollers, an actuating unit, and a detecting unit. The actuating unit can move the second driving roller between a released position, where the second driven roller is spaced apart from the second driving roller, and a contact, where the second driven roller contacts the second driving roller and is co-rotatable with the second driving roller to clamp and move a strap. The control device controls rotation of the first and second driving rollers to feed and return the strap, detects rotation of the first driven roller, and controls the actuating unit to move the second driven roller to the contact and released positions.

A filament feeding device (100) for use in 3D-printing comprising a first feeding wheel (110) configured to rotate with a first rotational shaft (112) and a second feeding wheel (120) configured to rotate with a second rotational shaft (122). The first and second feeding wheels (110, 120) are separated by a separation distance so as to allow feeding of a filament material received between said first and second filament wheels (110, 120). The filament feeding device further comprises an adjuster element (130) movable between a first distinct position (130a) setting said separation distance to a first predetermined distance, and into a second distinct position (130b) setting said separation distance to a second predetermined distance, and wherein said second predetermined separation distance is larger than said first predetermined separation distance. Further, a 3D-printer comprising such a filament feeding device is herein disclosed.

A system configured to position a tip of a cable. The system includes: a cable delivery system; a cable tip positioning module situated at a workstation in proximity to the cable delivery system; a pair of wheels operable to push a cable into the cable tip positioning module when a cable is in a nip between the wheels; an apparatus configured to hold the wheels; a motor operatively coupled to drive rotation of the wheels; and a proximity sensor configured to issue a cable present signal indicating the proximity of a conductor in the cable. The cable tip positioning module comprises a computer system configured to activate the motor to drive rotation of the wheels in a cable pulling direction in response to issuance of the cable present signal.

A device for imparting a torsional force onto a wire has a base and a support mounted so as to be rotatable with respect to the base around an axis of rotation. The axis of rotation coincides with a wire path extending through the base and the support. Further, a wire clutching device is mounted on the support and adapted to engage at a wire guided along the wire path, and a rotation mechanism is provided which is adapted for rotating the support with respect to the base.

A cable recovery machine, comprising at least one traction module configured to hold and draw at least one cable, in particular of a cable laying plant; the traction module comprises a frame on which one or more traction wheels and one or more idle wheels are positioned; between the traction wheels and the idle wheels a space is defined for the passage and traction of the cable to be recovered; the idle wheels are provided with a support connected in a mobile manner to the frame of the traction module and provided with actuators configured to press the idle wheels against the cable that passes between them and the traction wheels, so that the space between the idle wheels and the traction wheels can be automatically adjusted on the basis of the external diameter (D1, D2) or thickness of the cable drawn.

Cable handling devices, methods and systems are provided for securing and deploying, or retracting, one or more cables or hoses into or out of a pipe or cavity allowing inspection of the pipe or cavity. The cables and/or hoses may be coupled and moved together, or decoupled enabling them to be moved independently. A hand-held device with a housing for at least partially enclosing one or more cables or hoses, at least one coupling mechanism integrally attached to the housing, and a coupling control for coupling and decoupling the one or more cables or hoses may be provided. One or more of the cables may be connected to a camera disposed at the distal end of a cable thereby facilitating inspection of the pipe or cavity. Tools such as cutting devices or a jetter may be provided at the end of the one or more cables and/or hoses.

The present invention relates generally to medical equipment, more particularly, the use of fluid hoses coupling tanks to cannulas, as part of medical gas therapy, such as oxygen therapy. The invention describes a collection system for managing excess flexible hose that a patient might need to wear for medical reasons such as home oxygen medical therapy. It comprises a non-spooling roller system attached to a receptacle for collecting excess hose into the receptacle and extraction from the receptacle, and a power system to power and control the roller system, and design features that optimize the collection and extraction.
