Abstract:
An arrangement of an elongated element (10) wound on a spool(12) is presented. The elongated element (10) having a leading endcomprising a bent part (14)and an unbent part (16). The bent part (14)further comprises a beginning part (14a) and a trailing end (14b). The leading endispositioned on the core(11)of the spool (12)and the bent part (14)deviatesat least for a part from a winding direction(18). The elongated element(10)further formssubsequent windings (22, 23, 24, 25) in the winding direction (18) on the core(11). At least one of the subsequent windings (22, 23, 24, 25) iswound overthe beginning part (14a) ofthe bent part (14) while an adhesive (26, 27, 28) is provided to fix the trailing end (14b) of the bent part (14)on the core (11)simultaneouslythereby securing elongated element (10) on the spool(12).
Abstract:
An elongated element (10) is transferred from a second (full) spool (13) to a first (empty) spool (14). A a gripper (16) is positioned on the elongated element (10). The gripper (16) catches the elongated element (10) and the elongated element (10) is cut between the gripper (16) and the second spool (13) thereby leaving a leading end (19). Thereafter the gripper (16) is positioned with the leading end (19) at the level of the first empty spool (14). The gripper (16) is rotating around the axis of the first spool (14) to form first windings to fix the elongated element (10) on the first spool (14). The method allows full automation and assures the use of the wound element (10) until its final end.
Abstract:
The invention relates to a winding module and a winding installation comprising such winding modules for winding metal wire as e.g. steel wire of diameters between 0.5 to 3.0 mm on spools. In such a winding installation or take-up bench a driven capstan is used to pull the metal wire through a processing installation before being led onto a take-up spool. The spool is driven by a cantilever supported shaft. In prior art take-up benches, both the capstan and the spool is reachable by an operator from the same side. This means that the capstan direction – that is the direction from the driven side of the capstan to the operator side – is equal to the shaft direction - that is the direction from the drive side of the shaft to the open end of the shaft. In the inventive winding module the capstan direction is opposite to the shaft direction. The inventive arrangement allows for a completely different operation of the winding module and the winding installation and facilitates the introduction of doffing robots.
Abstract:
A spool fixation device (100) for use in a wire winding installation such as a steel wire processing installation is disclosed. In this spool fixation device spools having a magnetically attractable flange are held to a rotatable flange (102) by means of magnet assemblies (104, 104', 104", 104"'). Particular about the magnet assemblies is that they can be switched between a 'hold' state and a 'release' state. In a preferred embodiment the magnet assemblies only consume energy when in the 'release' state i.e. when the spool fixation device is not rotating. Alternatively the magnet assemblies can be made to only consume energy when switching states. The benefit is that when the spool is rotating no energy supply is needed. The magnet assemblies comprise permanent magnet arrays and are moveable inside a non-magnetic housing. Also a drive pin to transfer torque between rotatable flange and spool is no longer necessary. Therefore the spool fixation devices allows for a smooth changeover of spools.
Abstract:
3D porous material comprises at least one machined side. The machined side has a solid percentage P s being (1-P O ), said P O is the porosity of the bulk of said 3D porous material and said P s is within the 99.5% confidence interval. The present invention provides the method of manufacturing such 3D porous material. Preferably, the 3D porous material is open cell metal foam. The present invention also provides use of such open cell metal foam in a heat exchanger. The present invention further provides a heat exchanger comprising open cell metal foam.
