    The invention relates to a Kappsägeanordnung according to the preamble of claim 1.
    A crosscut saw assembly is part of a crosscut sander. Such Kappsägeanlagen be used to Schnittgut, for example, cut boards, so cut to the desired length. This cutting can be done further to cut off defective areas, such as knotholes on both sides of the clippings. Here, the clippings is guided on a conveyor, wherein the clippings is transverse to a conveying direction. For cutting to length, a chop saw is predeterminably brought from a waiting area into a sawing area, wherein the chop saw cuts the cut material in the sawing area. The removal of the chop saw from the waiting area in the sawing area is done very quickly in many machines. Conventional cross-cut saw assemblies have a pneumatic or hydraulic actuator.
    A disadvantage of such Kappsägeanordnungen that the movement is only partially controlled by the pneumatic or hydraulic adjustment of the chop saw. The movement is influenced by the different prevailing temperatures different and sometimes undefined, in addition there is a bouncing movement in the end positions, whereby the life of the system is shortened and flying chop pieces can hit parts of the system, such as hydraulic hoses.
    The object of the invention is therefore to provide a Kappsägeanordnung of the type mentioned, with which the mentioned disadvantages can be avoided, and a precise and reliable cutting of the cuttings is possible even at high process speeds.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that the removal of the chop saw from the waiting area in the sawing area can be performed quickly and in a controlled manner. In this case, a precise control of the actuator can be achieved, whereby quiet changes of direction of the actuator are possible. Furthermore, an actuator with an electric drive is less sensitive to 2/17 • · · · · · · · · · · · · · · · · · ·

    Temperature variations as a pneumatic or hydraulic drive, low maintenance and easier to install. This allows the process of cutting to be done quickly, reliably and economically. Furthermore, a bouncing movement in an end position of the actuator can be largely avoided, whereby a clean cut can be achieved and there is no unwanted damage to the cuttings, and also no damage to equipment by uncontrolled Kappholzteile the cuttings.

In this case, the carrying device 5 may in particular comprise a profile carrier or a forming tube. Furthermore, it can be provided that a plurality of cross-cut saw assemblies 1 are connected to one another by means of a support device 5, that is, a plurality of chop saws 2 are movably mounted on a support device 5, and thus form a cross-cut saw 13.
    It is provided that the actuator 6 comprises an electric drive 7. This means that the force for moving the chop saw 2 is effected directly electrically, that is, that the force is generated by an electric motor 8 and converted by means of a mechanism into a movement. It also means that not only an electrical control is provided in a pneumatic or hydraulic.
    This results in the advantage that the movement of the chop saw 2 from the waiting area 3 into the saw area 4 can be carried out quickly and in a controlled manner. In this case, a precise control of the actuator 6 can be achieved, whereby abrupt changes of direction of the actuator 6 can be avoided. Furthermore, an actuator 6 with an electric drive 7 is less susceptible to temperature fluctuations than a pneumatic or hydraulic drive, requires less maintenance and is easier to install. This allows the process of cutting to be done quickly, reliably and economically. Furthermore, a bouncing movement can be avoided in an end position of the actuator 6, whereby a clean cut can be achieved and there is no unwanted damage to the cuttings 15, and also damage 4/17 ·· ··· ♦ ► · · ► · · ·· 33971 / lh, mo of systems by parts of the cuttings 15 is largely avoided.

    Furthermore, it can be provided in particular that the chop saw 2 is designed as a circular saw. A circular saw has a rotating saw blade, with which the clippings 15 can be cut. In this case, a clean cut can be achieved with very few parts. Alternatively, the chop saw 2 can also be designed as a sword saw.
    Preferably, the actuator 6 to an electric motor, wherein both a rotary electric motor 8 and a linear motor can be provided.
    Particularly preferably, it can be provided that the actuator 6 in each case comprises a rotary electric motor 8, in particular a geared motor, which is connected by means of a push rod 9 with the chop saw 2.
