An apparatus for repairing or refurbishing a filter screen (of the type defined in the specification) is described, The apparatus comprises a tray for accommodating a filter screen frame (10) from which worn wirecloth has been stripped. Wirecloth stretching means surrounds the tray which includes attachment means for securing to edges of a sheet of wirecloth (159) laid over an upper surface of the frame (10) in the tray. Tensioning means is provided for exerting tension on the wirecloth (159) in at least two mutually different directions so as to stretch it over the frame (10), and heating means is provided for heating the frame (10) to soften the uppermost edges of a matrix of struts and periphery of the frame (10). Forcing means serves to force the wirecloth (159) into the softened edges such that after cooling, the wirecloth (158,159) remains bonded to the frame (10). Thereafter the wirecloth (159) can be trimmed back to the edges of the frame (10). A second attaching means and tensioning is provided to enable at least a second sheet of wirecloth (158) to be secured over the first wirecloth (159) for bonding to the frame (10), at the same time as the first wirecloth (159) is bonded to the frame (10). Additional means is provided for applying plastics material along each of the surfaces to which the new wirecloth (158,159) is to be attached, prior to, or after, wirecloth has been stretched over the support frame (10), so as to increase the amount of plastics material available to bond the wirecloth to the frame.
摘要:
The invention relates to a sieve (1) comprising a first stationary portion, receiving the screens, and a second portion (101) referred to as the cover, translatable (F3) between a first position of closure of the opening of the first portion and a second opening position enabling access to the screens. The invention comprises a first stationary transverse walkway (13) located at the bottom portion of the sieve and suitable for providing access to a first screen when the cover (101) is in the open configuration and to provide access from one side of the sieve to the other only when the cover (101) is in the closed configuration. It comprises at least one second transverse walkway (25) movable between a first position that prohibits access to at least a second screen when the cover (101) is closed and a second position, referred to as the active position, in which the second walkway (25) defines an access path to at least a second screen when the cover (101) is open, the second transverse walkway (25) also defining, in the active position, an access from one side of the sieve to the other, above the first transverse walkway (13).
