Beloit Removable Fourdrinier

N INTRODUCING our Removable Type of Fourdrinier, it is perhaps advisable first to consider the ordinary method used in changing a wire on the machine. As a1l paper makers know, it is necessary practically to wreck the Fourdrinier end In making this change. This change occurs every two to eight weeks, depending upon speed, good luck and a number of other factors. It ordinarily takes two to six hours to make this change, depending largely upon the length of the wire, its width, number of men used in making the change, their training in this particular line, as well as facilities for handling the various heavy parts.

HE time element, while important, does not tell the whole story. In old types of Fourdriniers, every roll has to be removed. This is a back-breaking job for the operators. It also takes the rolls out of their individual bearings, covers the operators and the rolls themselves with grease or oil and always entails the chance of damaging the rolls as they are. taken out put in The breast roll has to be removed and the heavy suction boxes taken out and handled carefully. When all of these parts are replaced after the wire is in place, there is always the possibility of dropping a roll through the wire or crimping the edge, besides the danger of pinching the operator's fingers as the various rolls and boxes are put back into place. To eliminate all this trouble, danger and time required, we have developed our Removable type of Fourdrinier. The Fourdrinier part is arranged so that by placing tracks on the front side of the machine, it is possible to run, by means of power, the entire Fourdrinier out to the front side of the machine, string the wire in place and then run the entire Fourdrinier back into the loop of the wire. The illustration at the top of this page shows the Fourdrinier with these rails in place.

Wire Changes made in an Hour or Less

  HE above illustration shows the arrangement of the couch rolls and housings for same when the conventional couchers are used. The illustration below shows the same feature from a different angle. With this type of Fourdrinier, it is possible, with the ordinary machine crew, to change a wire in an hour or less and absolutely eliminates the handling of rolls or suction boxes, besides overcoming the danger of injuring the wire.

 

N another bulletin is shown a method for handling the wire when a suction couch is used. This feature is without doubt the greatest advance made in recant years in the way of time and labor saving machinery in paper machine. If in the market for new equipment, consider the advantages of these modern features, and ask us to call and quote on your specifications.
