Definitions

• the present invention relates to a method for arranging spacers which are meant for being supplied to a table for receiving articles for stacking and/or articles during stacking.
• the spacers are of such a kind that usually form at least a basis for articles and intermediate elements between articles, which are to be stacked, packed or the like for further handling, stock-keeping, transportation, etc.
• spacers or so-called stickers are generally existing.
• spacers are used in manufacture industries and metal-working industries for elongated articles.
• the handling of the spacers is done manually or to a great extent manually.
• the spacers are often shaped in such a way that they by themselves can give rise to external damages on those articles with which they are used and/or are of such a kind or material that they are consumer or non-returnable goods.
• a method and a device in accordance with the present invention can fulfil the requirements made, while at the same time the disadvantages of known methods and devices are eliminated.
• One object with the present invention is thus to achieve a more rational handling of spacers and in addition results in a simpler and more rapid process and running through in the handling of articles, which have been produced or manufactured and will be taken care of for further handling, which in turn involves lower cost.
• Another object is to eliminate or at least reduce the risk for exterior damages on the articles, which damages can be caused by contact with other objects, with one another or by used spacers.
• the method and device are adjustable for laying out various kinds of spacers, different number of spacers and varying distances between the spacers so the method and device are suited for different kinds and shaping of spacers, different kinds, shaping and length of those articles with which the spacers will be used, different kinds and shaping of containers, in which the articles will be brought together for further handling, etc.
