Procedure and device for the wrapping os compressed bales

Abstract

A device for covering bales of unpacted fiber materials includes a winding device, which has spaced apart substantially parallel first and second rolls of bale covering material, on which a single covering material is wound such that the material extends between the two rolls of material. A bale of the fibrous material is formed on a support which, in one embodiment, comprises a carriage so that there is a relative movement between the bale support and the winding device, so as to cause the support with the bale to move through the plane of the covering material, thus, cause the material to wrap around the adjacent end and the sides, and up to the front end which is opposite the adjacent end. Covering material ends, which are arrived at the front of the bale are directed to a clamping device so that they are closed in the front of the bale. A closing is also advantageously effected by welding the ends together at the bale, thus, close the covering over the bale and to also sever the ends of the covering material away from the bale and to weld these ends together, so that the covering material may be used again. The invention also includes means for feeding both a top lid covering, and a bottom covering so that these coverings are directed against the bale as it is being compacted thereafter enclosed with the side covering material. A device for cutting the covering material as well as for welding it, and for welding together the severed ends of the covering material functions to effect one or more of these operations in accordance with the plant arrangement.
