ABSTRACT:
A method for producing a hollow-cylindrically shaped fibrous article stabilized by hot adhesion and an apparatus suitable to produce the same are provided. Said method comprises passing a web of gathered fiber layer carried on a conveyer belt through a heating zone, heating said web in such a way that a lower-melting component of composite fiber contained in the lower part of said web contacting the conveyer belt is not in the molten state and a lower-melting component contained in the upper part of said web is in the molten state, while separating said web from the conveyer belt, winding up said web on a take-up rod or tube in such a way that the upper surface thereof occupies the inner side of the winding, while heating the web further, cooling the wound up article and drawing out the take-up rod or tube from the shaped product.
The production method of the present invention is simple and does not require complicated apparatus and the resultant product is useful for filtration.
