摘要： A screen is described wherein one end of the screen frame is provided with an upwardly open channel profile and the other end with a similar but downwardly open channel profile, such that the outboard edge of an upwardly open profile will fit within the channel of a downwardly open profile provided along the edge of an adjoining screen frame, to enable two such screens to be connected together and to enable linear movement in a direction generally perpendicular to the line of engagement and generally in the plane of at least one of the two screens, to be transmitted from one screen frame to the other. The engagement of one profile by another also serves to close the gap between the two screen frames and prevent at least particulate material from passing therebetween. Preferably the engagement prevents liquid from passing therebetween. The engagement may comprise a lost motion connection so as to permit one frame to be hingeable relative to the other about the connection, but still provides a reliable force-transmitting connection to enable a rear screen frame to be removed from the support structure simply by pulling out the front frame of the pair.

摘要： A frame over which woven wire mesh is to be stretched and secured to form a sieving screen and which can be used to screen solids from drilling mud recovered from down-hole when drilling for oil or gas. The frame is a rectilinear moulded plastics frame having edge regions by which it is secured in place in a shaker. Within the frame is a plurality of rectilinear windows formed by an orthogonal array of intersecting ribs also of moulded plastics material. Some of the ribs are internally reinforced by rigid metal members which extend orthogonally between hollow box-section members which define a sub-frame for reinforcing the four edge regions of the frame. The ends of the sub-frame members are joined at the four corners of the sub-frame. In this way not are only the edge regions of the frame reinforced internally but so also are some of the orthogonally intersecting ribs, so as thereby to produce a rigid frame for the screen. The internal reinforcement for those ribs which are to be reinforced may comprise hollow box-section metal members which may be of similar cross section to that of the sub-frame members, or the internal reinforcement for those ribs which are to be reinforced comprises metal I-beam cross section members, which typically have the same height as the height of the box-section members forming the sub frame.

摘要： In a method of and apparatus for manufacturing a filtering screen, a frame of plastics coated metal or reinforced plastics material is located in a jig and at least two sheets of wire cloths are placed over the frame and their edges gripped by pneumatically operated clamps carried by the jig. The clamps are pneumatically driven outwardly of the frame to tension each cloth in orthogonal directions. The tensioned cloths are pressed against the frame and heated in order to bond the cloths to the frame. The heated material is allowed to cool, and after completion of the bonding step the clamps are released, allowing the frame to be removed from the jig. Where necessary the cloths are trimmed back to the edges of the frame. A separate set of pneumatically operated clamps may be provided for gripping all four edges of each wire cloth layer to allow each layer to be individually tensioned.

摘要： A method is described for making a reinforcing wire frame for embedding in a moulded polymer support frame (10) over which woven wire cloth (158,159) is to be stretched and secured to form a sifting screen. The method involves locating lengths of cut wire (50) substantially equally spaced apart in a jig to form a first array. A second array of lengths of cut wire (56,60) is located over the first array with the lengths of wire in the second array being substantially at right angles to those of the first array. The lengths of wire in the first and second arrays are resistance welded at points of mutual intersection so as to form a first substantially rectilinear matrix. Lengths of cut wire (48) are located in a jig to form a third array, in which the lengths are also substantially equally spaced apart, and a fourth array of lengths of cut wire (54,58,62,64) is arranged over the third array with the lengths of the fourth array substantially at right angles to the lengths of wire of the third array, and the wires of the third and fourth arrays are also resistance welded at points of mutual intersection to form a second substantially rectilinear matrix. Protruding lengths of wire on at least two sides of the four sides of one of the rectilinear matrices are bent using a press so as to bend each protruding length first in a generally upward sense and then at a point nearer its end in a generally downward sense so that an end region of each protruding length extends parallel to a plane of the matrix but is displaced therefrom. Thereafter the displaced ends of the protruding lengths of wire of one matrix are resistance welded to protruding lengths of wire of the other matrix, to form the frame.

摘要： A screen for use in a vibratory machine for separating particulate material from liquid material comprising a rigid rectangular support frame having flanges along all four edges to which screen cloths of the type described are bonded with the longer dimension of the rectangular openings defined by the warp and weft wires of the cloth parallel to the longer dimension of the frame. The frame includes an array orthogonal rigid interstices defining a plurality of similar sized rectangular openings or window and the cloths are also bonded to the interstices for the purpose of maintaining the length to width ratio of the openings in the cloths defined by the warp and weft wires thereof. The warp and weft wires of the cloths are tensioned before being bonded to the flanges and interstices.
