Abstract
An apparatus for manufacturing cellulosic fibrous material suitable for future compressing into a molded article which comprises a prepulverizing apparatus for cutting cellulosic material, a mixing chamber for mixing the prepulverized cellulosic material with a bonding material, a forming head for receiving the mixture from the mixing chamber and for dispensing the cellulosic fibrous material/binder mixture as a mat upon a moving carrier, a heating apparatus for heating the mat and a pressing apparatus for compacting and bonding the heated fibers in the mat.
Claims4
An apparatus for manufacturing a dry-shaped cellulosic fibrous transportable mat suitable for future compressing into a molded article, comprising:
- (a) a pre-pulverizing apparatus for cutting and forming cellulosic waste material in dry form into pre-pulverized material,
- (b) a mixing chamber and grinder for mixing said pre-pulverized material with a bonding material in dry form comprised of at least one thermoplastic bonding agent and one thermosetting bonding agent,
- (c) a forming head for receiving said mixture from said chamber and for dispensing the mixture as a layer upon a moving carrier,
- (d) a heating means for plasticizing the thermoplastic bonding agent in said layer without setting of the thermosetting bonding agent therein,
- (e) a pressure roller for compacting and bonding the layer into a transportable mat,
- (f) a cooling means for cooling said transportable mat, and
- (g) a cutter for cutting said transportable mat to select sizes.
