Claims10
The combination with a slip form concrete curb laying machine having a framework and, carried thereby, a hopper for receiving freshly mixed concrete and a chute therefrom having an opening for discharging the concrete in an upstanding shape, of a compressible sheet inserting apparatus supported by said machine and comprising a holder for releasibly retaining a compressible sheet of fibrous material beyond and above the discharge opening and perpendicular to the chute length, power actuated means for moving said holder vertically downwardly to force a sheet through the deposited concrete and paddle plates disposed as lengthwise extensions of the opposite sides of the chute and below said holder to bear against the opposite sides of the concrete and overcome bulging of the concrete as the sheet is inserted.
Apparatus for inserting a compressible sheet of material into a newly laid concrete curb comprising a holder for releasibly retaining a sheet of such material, power actuated means connected to said holder for moving the holder vertically downwardly to force a sheet through the deposited concrete and paddle plates disposed below said holder so that they will bear against the sides of the deposited concrete at the insertion point of a sheet.
