Abstract

An insulation system comprising: a supply of material having discrete elements; an applicator assembly for installation of the material having discrete elements to a surface; and a scrubber for finishing the face of the material, the scrubber including: (a) a vacuum conduit; (b) a blade assembly attached to the vacuum conduit; (c) a drive for the blade assembly; and (d) a vacuum substantially adjacent the face of the material during finishing. In the one embodiment, the system comprises a transporter system downstream of the supply of material having discrete elements for delivery of the material to the applicator assembly. Also, in one embodiment, the blade assembly comprises an axis of rotation perpendicular to the face of the material during finishing.

Claims

exact text as granted — not AI-modified
1 - 19 . (canceled) 
     
     
         20 . A scrubber for finishing the face of a material having discrete elements, the apparatus comprising:
 (a) a vacuum conduit;   (b) a blade assembly attached to the vacuum conduit, the blade assembly comprising an axis of rotation substantially perpendicular to the face of the material during finishing, said blade assembly including a plurality of blades extending outwardly from the axis of rotation and a planar blade attached to the distal ends of said plurality of blades;   (c) a drive for the blade assembly; and   (d) a vacuum substantially adjacent the face of the material during finishing.   
     
     
         21 . The apparatus according to  claim 20 , wherein the vacuum conduit includes at least one inlet and at least one outlet. 
     
     
         22 . The apparatus according to  claim 21 , wherein the open area of the inlet is greater than the open area of the outlet. 
     
     
         23 . The apparatus according to  claim 21 , further including a transition zone between the inlet and the outlet. 
     
     
         24 . The apparatus according to  claim 20 , wherein the blade assembly has contact surface substantially parallel to the face of the material during finishing. 
     
     
         25 . The apparatus according to  claim 24 , wherein the axis of rotation of the blade assembly is substantially perpendicular to the face of the material during finishing. 
     
     
         26 . The apparatus according to  claim 20 , wherein the blade assembly includes scalloped edges. 
     
     
         27 . The apparatus according to  claim 20 , wherein the blade assembly includes sidewall cutters. 
     
     
         28 . The apparatus according to  claim 20 , wherein the blade assembly includes an elastomeric surface. 
     
     
         29 . The apparatus according to  claim 20 , wherein the blade assembly includes an angled edge. 
     
     
         30 . The apparatus according to  claim 20 , wherein the drive is an external drive. 
     
     
         31 . The apparatus according to  claim 32 , wherein the drive is a belt drive. 
     
     
         32 . The apparatus according to  claim 33 , wherein the drive is a timing belt drive. 
     
     
         33 . The apparatus according to  claim 20 , further including a positioner attached to the vacuum conduit for moving the apparatus with respect to the face of the material. 
     
     
         34 . The apparatus according to  claim 33 , wherein the positioner includes at least one handle. 
     
     
         35 . The apparatus according to  claim 20 , wherein the vacuum includes a vacuum source attached to the vacuum for removing loose material created during finishing. 
     
     
         36 - 68 . (canceled)
