A fused deposition modeling filament production apparatus including an extrusion unit comprising an extruder, feeding means for feeding FDM raw material into the extrusion unit, a filament discharge at an end of the extruder, a filament cooling unit linked to the filament discharge, a filament buffer unit for receiving and storing the filament from the cooling unit. The extrusion unit, the filament cooling unit and the filament buffer unit are accommodated in a frame. The extrusion unit is horizontally accommodated in a top section of the frame, having the feeding means on top of the extrusion unit and extending vertically from the extrusion unit. The filament discharge is arranged for substantially vertically downward discharging the extruded filament from the extrusion unit. The filament cooling unit and filament buffer unit are accommodated in a lower section of the frame below the extrusion unit.

An apparatus and methods for pushing conductors into conduit and other structures are disclosed. The apparatus (pusher) can include rollers to apply a pushing force to one or more conductors or bundles of conductors. One or more rollers can be coupled to a drive mechanism. The pusher is configured to pull conductors or bundles of conductors off of one or more spools, and push the conductors or bundles of conductors without de-bundling or sorting the conductors. The conductors can be fed through the pusher in any format including side-by-side, vertical on top of one another, twisted together, or other formats. The pusher can include a guiding device that is configured to route the conductors from the pusher to a conduit through which the conductors are being pushed or pulled.

A system for axial positioning of a rotating shaft is provided herein. The system includes a first wheel. The system also includes a second wheel positioned adjacent to the first wheel such that the first wheel and second wheel are configured to rotate in opposite directions. The second wheel is also positioned such that first wheel and second wheel are configured to exert axial force tangential to the first wheel and the second wheel to a shaft positioned between the first wheel and the second wheel. Each of the first wheel and the second wheel each comprise a plurality of rollers positioned tangentially along a circumference of the first wheel and the second wheel.

It is intended to provide a cable pulling machine that can avoid, even when installed at a high place, a stop of pulling and a cable installation method. A cable pulling machine according to the present invention includes two roller portions c having outer peripheries between which a cable a is to be held and a guide f that introduces the cable a between the roller portions c. The guide f adjusts an angle ? formed between a straight line connecting respective centers o of the roller portions c and the cable a introduced between the roller portions c to a value of not less than 45? and not more than 90?.

A wire handling device for a manufacturing device includes an elongate first wire guiding device having a first guiding section for a wire to be guided along the first guide section, and an elongate second wire guiding device having a second guiding section for a wire to be guided along the second guide section. The wire handling device includes a support device, and the first wire guiding device and the second wire guiding device are placed on the support device. The support device is rotatably mounted about the rotational axis, and the first wire guiding device and the second wire guiding device are mounted so that they can be moved with respect to each other.

A portable rope drive and guiding apparatus operable by a single user is disclosed. The apparatus includes a receptacle defined by a first side wall, a second side wall, a first end wall and a second end wall, with a vertical opening between a top edge and a bottom edge for receiving the rope. The apparatus further includes a powered drive wheel mounted between the first side wall and the second side wall, and having a friction-bearing outer perimeter to drive the rope through the receptacle. The apparatus further include a guide wheel mounted between the first side wall and the second side wall, opposite the drive wheel, the guide wheel having a concave outer perimeter that corresponds to and guides the rope through the receptacle as the rope is driven by the drive wheel.

A cable pushing device is an apparatus that efficiently pushes a cable into a pipe with minimal effort. The cable pushing device includes a frame, a first wheel assembly, a second wheel assembly, and a cable guide system. The frame upholds the first wheel assembly, the second wheel assembly, and the cable guide system. The first wheel assembly and the second wheel assembly press against the cable and push the cable into the pipe. The cable guide system positions both the cable and the pipe onto the frame and between the first wheel assembly and the second wheel assembly. The first wheel assembly and the second wheel assembly are aligned with each other such that as the second wheel assembly is rotated by a user, the first wheel assembly applies press onto the cable, opposite the second wheel assembly, and consequently pushes the cable into the pipe.
