Definitions

  • the rods are so spaced that the portions thereof between the lug 36 and the enlargements 37 act as an annular series of teeth which are engaged by toothed driving belts 38 to rotate the support rod assembly.
  • Each rod is provided with a pair of rollers 39 rotatably mounted thereon adjacent the faces of the plates 33 which are opposed to one another.
  • the rollers 39 are located between the said opposed faces of the plates 33 and snap rings 40 engaged in recesses in the rods 35.
  • Each roller bearing assembly 43 comprises two roller members 44 the axes of which are at 90 to one another such that the outer peripheries of the rollers cooperate with respective portions of the V-shaped periphery of one of the plates 41.
  • the inner periphery of each plate 41 is formed with a series of regularly-spaced slots 45 for receiving the support rods 35 as described in greater detail below.
  • a number of spring loaded blade assemblies 46 corresponding to the number of supporting rods 35 are located between opposed portions of the plates 41 between the slots 45 therein.
  • the assemblies 46 comprise a pair of mounting brackets 47 secured to the members 41.
  • Each bracket 47 comprises a portion extending radially of the plate 41 and a foot portion projecting towards the opposite plate 41 from the radially outer end of the bracket.
  • a shield 73 is provided extending from the region of separation of the support rods 35 and the knife edged blades 49 after the discharge point of the formed bags,
