The invention relates to a device for continuous, jointless gluing of timbers along their narrow sides with a slider, the use of unconnected, Lumber provided with glue one after the other to a work table, the woods with hold-downs are resilient and a holding device as a backstop between the slide and the hold-down devices is provided.

A device of this type is known from DT-AS 10 45 076. Inside the hold-down a retaining member is provided there, which is under pressure from a spring and which acts as a backstop can be viewed for the board inserted last. However, this device is not suitable for Gluing wood of different thicknesses. Namely, a wood with a relatively large thickness of the insertion device is detected, the foremost edge of the hold-down device prevents insertion same. However, there is no provision for lifting the hold-down device. Becomes a wood proportionately Slightly inserted, the holding member descends on this wood. By the Lowering of the holding device and with the simultaneous relaxation of the spring, however, the effect of this Holding element as a backstop is no longer fully maintained. As a result, there is no constant Pressure is exerted on the wood to be glued. In this known arrangement is the The effect of the backstop depends on the deflection of the hold-down devices.

From GB-PS 1 04 236 there is a * that has a similar effect Device such as that described at the beginning has become known. In this known arrangement in any case, the processing of wood only with almost

of the type mentioned at the outset, which is characterized is that the hold-down device on the output side of the device is more resilient than on the input side and can be raised on the input side, and that the holding device is independent of the hold-down devices working backstop is designed

The main advantage of the invention is that the frictional force, which decreases in the insertion direction, acts on the Timber is compensated by the heavier load on the hold-down device on the output side, so that over the an approximately constant brake pressure is applied over the entire length of the device. This prevents one The individual pieces of wood go back when the slide goes back. This effect is made possible by the backstop which prevents the last inserted wood from moving in the opposite direction of the To move the slide. The additional weight of the hold-down device, which is the output cable, also prevents that the glued wood bulges up on the exit side, which also improves the quality of the Joints would suffer.

To increase the pressure on the output side of the hold-down devices, pressure cylinders on the output side act in an advantageous manner on each of the hold-down devices. , _; (So, furthermore, lifting cylinders can be provided on the input side, through which the hold-down devices are raised *?

The timbers 1 to be glued together are provided with Leira on their two narrow sides. Included a two-component glue can also be used, so that the steps shown in FIG. 1 v * oh right pointing The first narrow sides and the narrow sides pointing to the left carry the second component of the glue.

These woods 1 are by means of a slide, not shown, in the direction of arrow 2 in the actual Entering glue device, where they first get under the brake shoe 3 of the backstop 4, which is around the Axis 5 can be rotated in the direction of the double arrow 6

The subsequent hold-down 7 is ausgangssei tig loaded with an additional weight 8 with their On the underside, the pieces of wood S lie on the flat work table 9. Can be attached to the gluing device Connect a rotating circular saw to cut the endlessly manufactured band to length.

From Fig. 2, the slide 13 can be seen in particular.

which introduces the pieces of wood 1 in the direction of arrow 2 into the device

Under a carrier 14 is the one shown in FIG. 2 backstop, not shown. The braking device is formed by individual hold-down devices 7. There are lifting cylinders on the insertion side 15, with which the braking device can be raised. On the output side there are pressure cylinders 16, which act in the direction of the additional weight 8 during operation.

A beam 17 is guided between guides 18. The pressure cylinders 16 are on this beam 17 attached The pressure cylinders 16 then form the additional weight 8 shown schematically in FIG this arrangement is then, according to the description, a seamless gluing of woods 1 different Thickness possible with approximately constant gluing (or pressing) pressure.
