Welding group for (coextruded) keder
Applies a coextruded profile to the upper side of the mesh while the grip-and-pull system pulls the insect screen from the roll. A customized guide and roller mechanism makes sure the profile is applied with great precision and that the seam is strong and aesthetically impeccable.
Pocket welding group w/ automatic insertion of reinforcing tube
Automatically welds a folded PVC strip to the lower, or to the upper side of the screen. While the grip-and pull system pulls the screen from the roll and spreads it on the table top, a guide and roller will fold the strip and automatically insert a tube, thus creating the pocket with which the mesh is attached to the lower hand grip of the insect screen. This operation is done fast, precise, and without any intervention of the operator whatsoever. Guides and rollers are custom built, according to your production requirements.
Welding unit for lateral reinforcing strip
Automatically applies a reinforcing strip to the left and right sides of the insect screens. The motorized rotary knife with pentagonal blade runs across the width of the table and cuts the strip straight through the middle, thus creating the left side reinforcing strip of the finished piece, and simultaneously the right side strip of the subsequent piece.
Motorized rotary knife
Cuts the insect mesh off of the roll. When the grip-and-pull system has pulled the fabric to the programmed length, a pressing bar secures the fabric in place. The motorized rotary knife now makes a fast, very precise cross cut along the width of the table. With its razor sharp pentagonal blade and the high speed with which it rotates, the motorized rotary knife makes a fast, high precision cut.
Automatic rewinding unit of the cut and welded insect mesh on the aluminum bar
Automatically rewinds the cut-and-welded insect screen on the aluminum bar. An electronic sensor in the table surface recognizes the end of the fabric and automatically stop the rotating motion a fraction of a second later. With this accessory an otherwise very time consuming and imprecise step in the production cycle is carried out fast and with great precision.
Pneumatic mechanism for the automatic positioning of a new aluminum bar
The structure can hold up to 20 aluminum bars. At the end of every cycle this device will automatically put a new aluminum bar in position, ready for the upcoming cycle. A series of pneumatic cylinders will make sure that every new aluminum bar is placed smoothly and silently.
System for the semi-automatic insertion of the rolled up insect screen in the box and the automatic attachment of the lower hand grip
An (optional) station inserts the rolled up insect screen in the box and automatically attaches the lower hand grip to the screen. This station carries out an otherwise difficult to manage and time consuming operation and completes the production cycle.
