Abstract

A method and equipment for manufacturing floor underlayment is provided. The equipment is configured to produce floor underlayment having a consistent density and thickness. The equipment has a series of rollers configured to pull a formed batt into a moving transverse blade and to cut the underlayment into two portions having random fiber distribution and even thicknesses and densities.

Claims

exact text as granted — not AI-modified
1 . A machine for slicing a batt of material into two pieces comprising:
 a moving saw blade;   a table which slidably accepts the batt of material;   a pair of pulling rollers disposed on top and bottom surfaces of the material batt, wherein the pulling rollers pull the material batt off of the table and push it against the moving saw blade in a first direction; and   a biasing member that biases the moving saw blade toward the material batt in a second direction that is opposite of the first direction, wherein the moving saw blade cuts the material batt into two separate pads having a thickness about half the thickness of the batt.   
     
     
         2 . The machine according to  claim 1  further comprising a series of guides to ensure the pads do not engage one of the pulling rollers and the moving saw blade, after the material batt is sliced. 
     
     
         3 . The machine according to  claim 1  wherein the pulling rollers are driven by at least one roller, rotating in a direction opposite to the direction of the pulling rollers. 
     
     
         4 . The machine according to  claim 1  further comprising a blade jaw defining a channel, wherein the moving saw blade is a band saw blade supported in the channel. 
     
     
         5 . The machine according to  claim 4  wherein the biasing member is a spring-loaded carbide pusher disposed within the channel and supporting the band saw blade. 
     
     
         6 . The machine according to  claim 1  wherein the pads are treated after being formed by splitting the material batt. 
     
     
         7 . The machine according to  claim 1 , the table has a tapered nose portion disposed between the pulling rollers. 
     
     
         8 . A machine for slicing a batt of material into two pieces comprising:
 a moving band saw blade;   a table having a top surface which slidably accepts the batt of material;   a pair of pulling rollers disposed on top and bottom surfaces of the material batt, wherein the pulling rollers pull the material batt off of the table and push it against the moving band saw blade in a first direction; and   a biasing member that biases the moving band saw blade toward the material batt in a second direction that is opposite of the first direction, wherein the moving band saw blade cuts the material batt into two separate pads.   
     
     
         9 . The machine according to  claim 8  further comprising a series of guides disposed adjacent the pulling rollers to ensure the material batt and pads do not engage the pulling rollers or the moving band saw blade after the material batt is sliced. 
     
     
         10 . The machine according to  claim 8  wherein the pulling rollers are rubber and are driven by at least one roller, rotating in a direction opposite to the direction of the pulling rollers. 
     
     
         11 . The machine according to  claim 8  further comprising a blade jaw guide defining a channel, wherein the moving band saw blade is supported in the channel. 
     
     
         12 . The machine according to  claim 11 , wherein the jaw guide has a tapered nose portion disposed between the pulling rollers. 
     
     
         13 . The machine according to  claim 11  wherein the biasing member is a spring-loaded carbide pusher disposed within the channel and supporting the moving band saw blade. 
     
     
         14 . The machine according to  claim 11  wherein the pads are treated after being formed by splitting the material batt. 
     
     
         15 . The machine according to  claim 11  wherein the table has tapered surfaces and the jaw guide has a tapered nose portion disposed between the pulling rollers and located opposite of the tapered surfaces of the table. 
     
     
         16 . The machine according to  claim 1  wherein the biasing member is a spring-loaded carbide pusher. 
     
     
         17 . The machine according to  claim 1  further comprising a blade jaw guide defining a channel, wherein the moving saw blade is supported within the channel. 
     
     
         18 . The machine according to  claim 17  wherein the biasing member is disposed within the channel and supports the moving saw blade. 
     
     
         19 . The machine according to  claim 1  wherein the material batt is a batt of underlayment material, and the pads are underlayment pads. 
     
     
         20 . The machine according to  claim 8  wherein the biasing member is a spring-loaded carbide pusher. 
     
     
         21 . The machine according to  claim 8  wherein the material batt is a batt of underlayment material, and the pads are underlayment pads. 
     
     
         22 . The machine according to  claim 11  wherein the biasing member is disposed within the channel and supports the moving band saw blade.
