摘要： A strip of filter material is folded so as to form two closely adjacent strip portions which are of one piece and have aligned longitudinally extending free edges and longitudinally extending second edges transversely spaced from the free edges and unitary with one another. The strip is coiled so that each of the strip portions forms a plurality of convolutions which alternate with the convolutions of the other strip portion. Means is provided in the region of the second edges for preventing liquid being filtered from forcing contaminant particles through the filter material.

摘要： A method of making a liquid filter includes the steps of providing a spiral roll of filtering material on a central tubular member, providing a housing member into which the roll is to be placed and laying a bead of thermoplastic material having a given softening point on an outer surface of the roll at least around the circumference of the roll close to an end thereof. The bead is pressed with cooled forming jaws, while in a warm state, to suitable dimensions corresponding to inside dimensions of the housing member. The housing member is heated to a temperature above the softening point of the thermoplastic material, the roll is inserted into the housing member and thereafter, the housing member is cooled. The thermoplastic material cools, acts as a glue and constitutes a tight, rigid connection between the housing member and the roll of filtering material.
摘要翻译：制造液体过滤器的方法包括以下步骤：在中心管状构件上提供过滤材料的螺旋卷，提供容纳构件，辊将被放置到其中，并将具有给定软化点的热塑性材料珠填充在辊的外表面至少围绕辊的圆周接近其端部。在冷却的成形爪的同时，将胎圈按压到合适的尺寸，以适应与壳体的内部尺寸相对应的尺寸。将壳体部件加热到高于热塑性材料的软化点的温度，将辊插入壳体部件中，之后将壳体部件冷却。热塑性材料冷却，作为胶水，并在壳体构件和过滤材料卷之间构成紧密，刚性的连接。
