The invention relates to an apparatus for manufacturing an oil spill boom as further defined in the preamble of claim 1.

The ability of peat to absorb oil from the water surface has long been known and therefore peat has been used in the manufacture of oil spill booms as an oil absorbing component. In the production of such an oil spill boom, the method has in principle been to insert peat into a sparsely woven, reticulated textile fabric hose, so that a boom filled with peat of the desired length is obtained. The production has mainly taken place by hand using a suitable funnel and pestle, with which the peat has been inserted into the hose a little at a time.

However, such a method is very slow and becomes expensive as well as limiting production.

The object of the present invention is therefore to provide a device with which the manufacture of an oil spill boom can be carried out quickly and efficiently.

The invention is mainly characterized by what is set forth in the characterizing part of claim 1.

An embodiment of the invention is illustrated in the following description with reference to the accompanying drawing, which schematically shows a side view of a device according to the invention.

The device according to the invention mainly comprises a screw feeder known per se, the body of which is formed by a pipe 1 of suitable length, which may be metal or even plastic.

The frame tube 1 is fixed to the machine base 2, preferably in a horizontal position, in order to obtain a suitable working height. A relatively large pitch screw 3?, Which is known per se, is arranged inside the pipe. which is driven at the end of the shaft 4 by means of a motor 8 via a pulley 5 and a belt 6. The feed screw 3 is mounted on the pipe 1 in a manner known per se. A feed opening 9 is made above the pipe 1, in which a feed hopper 10 is arranged for feeding peat to the pipe 1.

The front end 11 of the pipe is made to protrude freely, e.g. by a distance of approx. 1 m, so that a peat-filled mesh hose 12 can be pulled into the front end when the feeder is running and peat is fed to the protruding pipe end into the pleated blank hose 12. :. is fulfilled.

According to the invention, the shaft of the feed screw 3 is made tubular, whereby a string or wire 14 can be passed through this tubular shaft, which continuously flows during filling and finally remains inside the hose, reinforcing it. The support rope can be fed in another way. The rope can be tied or attached to the ends of the hose, in which case it can be used to attach or extend the oil spill boom.

The front end 11 of the tube 1 is slippery or retaining coated so that the hose 12 can be properly detached therefrom. In order to adjust the filling tension, e.g. spring-loaded, adjustable brake shoes 13 can be arranged around the front end of the tube, with which the hose blank to be filled can be held with the required force.

Claims (1)

3 64419 The shape and dimensions of the device may vary within the scope of the invention. Claim: Apparatus for manufacturing a boom, comprising a motor-driven screw feeder mounted on a base, the feed pipe (1) being adapted to protrude from another frame structure, whereby a reticulated hose blank (12) can be folded over the pipe to fill it with porous material, e.g. means for supplying a longitudinal strip of hose during filling of the hose, characterized in that said strip is a support wire or rope (14), the feeding of which is arranged from inside the supply pipe (1) most preferably via the hollow shaft (4) of the feed screw.
