Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A METHOD OF ASSEMBLING A BATT, WHICH METHOD COMPRISES THE STEPS OF ESTABLISHING A PRESSURE DIFFERENTIAL ACROSS A GENERALLY UPRIGHT SCREEN, PROJECTING FIBROUS MATERIAL AT HIGH VELOCITY THROUGH SPACE TOWARD SAID SCREEN, ADVANCING UPWARDLY UPON SAID SCREEN FIBROUS MATERIAL ADHERING THERETO, DISLODGING AND REARRANGING FIBROUS MATERIAL ON THE SURFACE OF THE MATERIAL ADVANCING UPWARDLY ON SAID SCREEN, ACCUMULATING FIBROUS MATERIAL WHICH FAILS TO ADHERE TO SAID SCREEN AND ADVANCING SUCH MATERIAL TOWARD SAID SCREEN AT A LOWER LEVEL THAN THAN THAT AT WHICH FRESHLY ARRIVING FIBROUS MATERIAL IS PROJECTED THEREON, THE SAID PRESSURE DIFFERENTIAL CASUSING SAID ACCUMULATED AND PREVIOUSLY NON-ADHERENT MATERIAL TO CLING TO SAID SCREEN IN THE PATH OF NEWLEY ARRIVING PROJECTED MATERIAL AND SUBJECT TO THE IMPACT THEREOF.

Claim 3
Dependent Claim
159 words
A BATT FORMING DEVICE COMPRISING MEANS FOR MOVING FINELY DIVIDED FIBERS OF BATT FORMING MATERIAL IN A GENERALLY HORIZONTAL DIRECTION, A GENERALLY VERTICAL CONVEYOR SCREEN TOWARD WHICH SAID BATT FORMING MATERIAL IS DELIVERED BY SAID MEANS, MEANS FOR MOVING SAID VERTICAL SCREEN IN AN UPWARD DIRECTION, A VACUUM BOX BEHIND SAID VERICAL SCREEN TO DRAW SAID BATT FORMING MATERIAL PNEUMATICALLY AGAINST SAID SCREEN TO FORM A RELATIVELY THICK BATT THEREON, FIRST MEANS FOR METERING THE BATT FORMING MATERIAL TO ESTABLISH A PREDETERMINED BATT THICKNESS ON SAID VERTICAL SCREEN, SECOND MEANS TO REDUCE THE THICKNESS OF THE BATT TO SUBSTANTIALLY ITS FINAL DIMENSION AND THEREBY ALSO TO INCREASE AIR FLOW THROUGH THE REMAINING MATERIAL, SAID SECOND MEANS INCLUDING MEANS TO DISLOGE BATT FORMING MATERIAL FROM SAID BATT AND REARRANGE IT IN THE PRESENCE OF GRAVITY AND THE FLOW OF AIR TO SAID VACUUM BOXFOR REDEPOSIT OF SOME OF THE DISLODGED MATERIAL ON PORTIONS OF SAID BATT BELOW SAID SECOND MEANS.
