| A filter paper cup manufacturing machine produces filter paper cups containing a brewing material. The filter paper cups have similar depth and diameter. The machine exercises ordered steps of first cutting a receptacle portion and then forming a recess in the receptacle portion for receiving the brewing material. Performing the cutting step first facilitates forming the recess because surrounding filter paper which would resist forming the recess has been eliminated. | ||||||

| 50 | Filter medium forming system and process | US236376 | 1988-08-25 | US4940500A | 1990-07-10 | Shigeo Tadokoro; Joji Morioka; Hideyuki Takahashi |
| A filter medium forming system for forming a filter medium of the type wherein pleats radially outwardly extends in which sides of the pleats are alternately bonded at the inner and outer peripheral sides to allow fluid to be filtered flows generally along the length of the pleats. The filter medium forming system is comprised of a scoring device for forming linear depressions (score lines) on the opposite side surfaces of an elongate sheet-type filter medium. The scoring device is followed by an adhesive applying device for applying adhesive onto the opposite side surfaces of the filter medium at the edge sections. The adhesive applying device is followed by a pleating device for pleating the filter medium along the linear depressions to form a pleated filter medium having a plurality of pleats each having two sides contiguous through each linear depression. The pleating device is followed by a pressing device for tightly contacting the predetermined sections of the sides of each pleat to bond the predetermined sections with each other with the adhesive. Such a filter medium forming system is suitable for mass production for filter elements while making possible to form the flat filter medium into a predetermined pleated shape at high speed and with high accuracy. | ||||||
| 51 | Accordion pleated fluid filtering element | US912092 | 1986-09-29 | US4936991A | 1990-06-26 | Richard H. Peyton; Horace M. Misturado |
| A liquid filter includes a filtering medium of a collapsed cylindrical form which defines cooperating accordian pleats that form contaminant collecting walls. The medium is self-supporting, and divides the filter into inlet and outlet chambers across the medium. When the restriction of the medium increases, thereby increasing the pressure differential across the medium, the accordian pleats collapse until corrugations on the pleats engage with one another, thereby resisting further collapse of the medium. As the pressure differential increases still further to the extent that the corrugations are collapsed, a part of each fold is kept apart by adjacent double thickness portion of the fold or pleat, so that a minimum flow of liquid through the filter is maintained. | ||||||

| A method and apparatus are disclosed for providing a crimp seal pleated filter assembly having a two piece housing with a filter media disposed within the housing and having a plurality of alternating pleats. The apparatus includes a first and second jig for supporting the housing halves and an odd number of at least three or more movable pleat forming blades on one side of the apparatus. The odd number of blades are movable through one of the supporting jigs with blade edges opposing the other supporting jig. The odd number of blades includes an independently movable center blade and a first pair of outer blades with opposing surfaces of adjacent blades defining a first plurality of pleat forming spaces. An even number of pleat forming blades are positioned with blade edges opposing the first plurality of pleat forming spaces and are spaced apart from and in alignment with the opposing pleat forming blades. The even number of pleat forming blades includes at least a pair of center blades which project through the other supporting jig during pleat formation and define a pleat forming space in which a first center pleat is formed. The blades and the jigs are moved toward one another in a predetermined sequence for the blades to form desired pleats within a filter media and for the jigs to urge the filter housing around the pleated filter media to crimp seal and encapsulate the media within the housing. | ||||||
| 53 | Process and apparatus for capping filter elements | US33759464 | 1964-01-14 | US3354012A | 1967-11-21 | FORMAN HERBERT L; PALL DAVID B |
| In a continuous process for capping tubular filter elements, Fig. 2 (not shown) the caps 3 are fed in a series from a storage reservoir 2 to a stage 8 where a bonding agent e.g. thermosetting, themo-plastic resins and thermo-plastic binders, is ejected onto the caps from a dispenser 9. The bonding agent is uniformly distributed on the cap and maintained flowable by heating during transit over section 23 i.e. between stage 8 and a point D, where an operator pushes a filter cylinder firmly into the pool of bonding agent. The composites are fed over section 27, suitably heated to effect the curing of the bonding agent. On reaching an accumulation table 30, the composite is retrieved, inverted and the remaining open end of the tube is pushed into another cap, the seal being likewise effected. In a modification Fig. 1 (not shown), two assembly lines are provided. The rate of travel of the caps over the sections | ||||||
