Apparatus and method for manufacturing coil screens

An apparatus for manufacturing coil screens comprising:

• a working surface having a first edge and a second edge;
• a joining device, which is structured and arranged to deposit coils on the working surface, being movable over the working surface in a direction of movement from the first edge to the second edge;
• a slider, which is arranged on the working surface at least in a region of the first edge, being movable perpendicularly to the direction of movement of the joining device;
• and
• a holding-down arm, which is positionable in a region of the slider, that is structured and arranged to be movable between a covering position, in which the coils positioned on the working surface are covered, and a release position, in which the coils positioned on the working surface are accessible by the joining device.

A method for manufacturing coil screens comprising:

• consecutively depositing multiple coils side by side on a working surface via a joining device movable over the working surface in a direction of movement from a first edge of the working surface to a second edge of the working surface, whereby the multiple coils are brought into engagement with one another;
• and
• before the joining device begins depositing a new coil, displacing the coils, at least at their ends adjacent to the first edge, transversely to their longitudinal direction,
• wherein the displacing of the coils comprises activating a slider to push the coils a distance corresponding to a width of the displacement spur, and
• wherein, during the displacing of the coils, the method further comprises placing a holding-down arm into a position to prevent the deposited coils from being dislodged from the working surface.

An apparatus for manufacturing coil screens comprising:

• a working surface having a first edge and a second edge;
• a joining device structured and arranged to deposit coils on the working surface during movement over the working surface from the first edge to the second edge, the joining device including a displacement spur having a largest width of about one-half of a width of the deposited coils;
• a slider arranged on the working surface that is movable perpendicularly to the direction of movement of the joining device to move the deposited coils to form an overlap region in successively deposited coils on the working surface;
• a fixing wire insertion device structured and arranged to insert a fixing wire through the overlap region to fix the successively deposited coils on the working surface;
• a holding-down arm structured and arranged to, in an active position, cover the deposited coils to prevent them from moving away from the working surface while the slider is operating;
• and
• a coil securing arm structured and arranged to, in an active position, clamp the deposited coils on the working surface while the slider is not operating.
