Description

469 828 2 disturbances, and is used only for small feed capacities respectively for discontinuous operation. Thus, they are for the most part not suitable to be inserted into continuously working production facilities.

The object of the invention is to create a method and a for its implementation uncomplicated, safe functioning device for performing the cutting and the subsequent the 90 ° rotation of the slats in the manufacture of mineral wool products with vertical fiber orientation, which can be used for the lamination of raw fiber mats, as well as for lamination of cured fiber mats, which can be incorporated into a continuous production process in the main production plant which are also useful in post-connected transmissions. processing plants.

The method according to the invention and the associated the device enables a 90 ° rotation of the cut the slats in immediate connection with the cutting process, without tipping the slats or in any other complicated way must be turned.

The process is characterized in that it is supplied in forced mode the fiber mat is discharged above the highest point on a rising transport device, whereupon at the highest point a separation of a desired length takes place, which length corresponds to the thickness of the laminated finished product, whereupon the separated lamellae a removal device is applied, which is arranged inclined at an angle of about 90 ° to the the supply device. Through the arrangement of supply respectively the removal devices at an angle of about 900 in relative to each other, the change in fiber direction likewise by an amount of 90 °, without any complicated rotational movement must be performed.

The device according to the invention for carrying out the method mainly consists of a transport device intended for supplying the mineral fiber mat, which in the case of raw fiber mats il 469 828 3 at the same time serves as a pre-compression device, to which a cutting device is connected, which in turn consists of a pendulum top knife and a fixed bottom knife, as well as available there is a special transport device for the removal of the cut and again next to each other the slats, which is either designed as a sloping plane, which compression funnel or as a lashing station, as the case may be the desired purpose of use. The knife holder on which the upper knife is rigidly mounted, is arranged like a pendulum, so that it, in conjunction with the permanently mounted lower knife, cut the carpet into slats with a thickness corresponding to it laminated finished product thickness, and which is adjustable to cut to the desired length of the slats.

The device according to the invention is shown schematically in attached the drawing.

Mineral wool mats l or any other type of fibrous mats is conveyed by means of a transport device 5, which at flexible carpets (raw fiber mats and hardened fiber mats with low density and low binder content) are preferably designed with a steep slope and with a rounded shape, to the one at the highest point located the cutting device, which consists of a pendulum suspended top knife 3, and a fixed bottom knife 4. The highest point of the device is then identical to the position of the cutting edge of the fixed lower knife 4.

The setting angle of the transport device 5 and the radius thereof rounded parts are optimally adapted to the fiber mat material properties. As a rule, performed to a small extent bendable, rigid carpets l, via a gradually ascending, sloping plane to the highest point.

To prevent unwanted material movements, transport the device 5 equipped with upper transport rollers 8 (or conveyor belt), until immediately before the the device, between which roll the fiber mat 1 in defined forced position is maintained during transport and during cutting. 469 828 4 Through forced control, pre-compression takes place at the same time. the upper knife 3 is rigidly mounted to a pendulum knife holder 6, which is adjustable to cut slats of the desired length, corresponding to the desired thickness of the laminated finished the product. The upper knife 3 cuts it continuously via it highest point advanced fiber mat 1 in conjunction with it rigidly mounted lower knife 4 for dimensional slats 2.

Different product thicknesses are achieved by adjusting the pendulum the movement of the knife holder 6 with the upper knife 3 in relation to the transport speed of the fiber mat 1. The blow of the upper knife after cutting and the knife and knife the geometric shape of the holder 6, ensures a secure alignment of the separated slats 2 next to each other on the transport the device 7, to form an endless mat again. Through the position displaced by about 90 ° for the two transport the devices 5, 7, are provided after the cutting a vertical oriented fiber direction in the slats. As sought after quality.confection.of the later achieved product, the removal device 7 is designed as a final device. the planes, such as compression funnel or at the same time as masking device.

In the example, the laminated raw fiber mat is added to the following the curing chamber on a sloping plane.

The method and the associated device are characterized by a uncomplicated, unobjectionable and to a large extent complication-free solution. The device allows adaptation to all conventional conditions relating to it desired end product.

To ensure a safe cut by means of the top knife 3, there is also the possibility to set the knife in one defined angle relative to the carpet, to achieve a more cutting-like separation of the slats 2. In addition there is the possibility of further spraying or in another way moisten the slats with adhesive, either just before 'u 469 828 5 the cut or shortly after, ooh either on one side or on both sides, to ensure a better joining of the slats 2 between them.

Furthermore, slats can also be cut in other ways, which only 900 must be turned, supplied, removing the knife and a pendulum body similar to the knife holder takes over the transport the change of direction.
