Abstract
Abstract Apparatus is described for manufacturing a liquid treating unit including a plurality of rows of parallel channel members secured between sidewall members with successive rows inclined in opposite directions and separated by a sidewall member. The apparatus includes a jig for supporting the channel members of one row and a pair of support plates pivotally mounted on opposite sides of the jig for supporting a pair of sidewall members to enable attachment thereof to the side edges of such channel members and formation of a channel module. Air pressure instead may be employed for supporting the sidewall members in engagement with the channel members. The members may be of plastic material and are attached together by a solvent sprayed from nozzles attached to the jig or by thermal fusion with electrical heating strips. However it is also possible to use members of cardboard or treated paper and attached by a suitable glue. A plurality of channel modules are connected together by additional rows of channel members to form the complete unit in several steps with the same apparatus. However, in one embodiment, all of the modules forming the unit are made simultaneously by employing a plurality of jigs, successive ones of which hold rows of channel members inclined in opposite directions and are mounted on two jig supports that are moved relative to each other to enable removal of the completed unit.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
47 words
Apparatus in accordaNce with claim 1 in which the sealing means is a means for simultaneously attaching all of the channel members between the pair of wall members to form a row of channels by sealing the side edges of said channel members to said wall members.
Claim 2
Dependent Claim
67 words
Apparatus in accordance with claim 1 in which the support means includes movable support means for moving between a first, open position extending lateral to the sides of the jig means, wherein the sidewall members are spaced from the channel members, and a second, closed position substantially parallel to the sides of the jig means wherein said sidewall members engage the side edges of the channel members.
Claim 3
Dependent Claim
29 words
Apparatus is accordance with claim 1 in which the support means includes air pressure means for holding the sidewall members in engagement with the channel members by air pressure.
Claim 4
Dependent Claim
57 words
Apparatus in accordance with claim 4 in which the air pressure means includes closure means provided on the jig means for forming a plurality of vacuum chambers with the sidewall members and a plurality of spaced jig members in said jig means, and vacuum means for providing said chambers with a lower pressure than the surrounding atmosphere.
Claim 5
Dependent Claim
57 words
Apparatus in accordance with claim 5 in which the closure means includes a plurality of end plates pivotally mounted adjacent the upper ends of the jig members for closing the top of the jig means to enable a vacuum to be formed in said chambers and for opening said top to enable removal of the treating unit.
Claim 6
Dependent Claim
37 words
Apparatus in accordance with Claim 1 in which the jig means supports the channel members with their ends in two parallel planes and with said channel members inclined at an acute angle with respect to said planes.
Claim 7
Dependent Claim
66 words
Apparatus in accordance with claim 7 in which the jig means includes a plurality of jig members supported in a row and inclined in the same direction, said jig members being spaced apart to provide guide slots between adjacent jig members, said slots having widths approximately the same as the thickness of the channel members to enable said channel members to be held in said slots.
Claim 8
Dependent Claim
39 words
Apparatus in accordance with claim 3 in which the movable support means includes a pair of support plates pivotally mounted by pivot means on the opposite sides of the jig means for pivoting between said open and closed positions.
Claim 9
Dependent Claim
27 words
Apparatus in accordance with claim 9 in which the pivot means of each support plate has a pivot axis parallel to the sides of said jig means.
Claim 10
Dependent Claim
90 words
Apparatus in accordance with claim 10 in which the pivot means are adjustable to vary the distance of their pivot axis from the jig means in order to change the spacing between the support plates and the side of the jig means in said closed position to enable two previously formed treating units to be supported so that one of the sidewalls of each unit engages the opposite sides of the channel members to enable a larger unit to be formed thereof which includes at least three rows of channels.
Claim 11
Dependent Claim
35 words
Apparatus in accordance with claim 2 in which the sealing means includes applicator means for applying a bonding liquid to the seal region between the side edges of the channel members and the wall members.
Claim 12
Dependent Claim
42 words
Apparatus in accordance with claim 12 in which the applicator means includes a plurality of spray nozzles attached to the jig means for spraying said bonding liquid on at least the top of the side edges of each of said channel members.
Claim 13
Dependent Claim
27 words
Apparatus in accordance with claim 13 in which the bonding liquid is a solvent for the plastic from which the channel members and wall members are made.
Claim 14
Dependent Claim
23 words
Apparatus in accordance with claim 2 in which the sealing means includes heater means for fusing the channel members to the sidewall members.
Claim 15
Dependent Claim
47 words
Apparatus in accordance with claim 15 in which the heater means includes a plurality of electrical heating elements supported on the opposite sides of each of a plurality of spaced jig members forming said jig means in position to heat the side edges of said Channel members.
Claim 16
Dependent Claim
69 words
Apparatus in accordance with claim 2 which also includes feeder means for supplying the sidewall members, including a pair of spools of sheet material rotatably mounted on opposite sides of he jig means adjacent said support means for feeding the two sheets onto said support means, and cutting means for cutting off the end portions of said sheets on said support means to form said pair of wall members.
Claim 17
Dependent Claim
61 words
Apparatus in accordance with claim 17 in which the sheets and wall members formed therefrom are of plastic material, said wall members being supported on a pair of support plates pivotally mounted on the opposite sides of the jig means for pivoting between said open and closed positions and being sealed to channel members of plastic material in said closed position.
Claim 18
Dependent Claim
148 words
Apparatus in accordance with claim 1 in which the jig means includes a first jig holder having a plurality of jig members mounted thereon to form a plurality of first rows of spaced jig members inclined in a first direction, a second jig holder having a plurality of second rows of spaced jig members inclined in a second direction opposite to said first direction which are positioned between and spaced from said first rows to enable sidewall members to be supported between the adjacent first and second rows and to enable channel members to be supported between adjacent jig members for attachment between said sidewall member to form a multiple row treatment unit having a plurality of rows of inclined channels with adjacent rows inclined in opposite directions, and means for moving said jig holders relative to enable removal of said multiple row unit from said jig means.
