  • the collected fiber material is carried out of the branch 3 with the revolution of said belt 5 and delivered to the dish plate of the carding engine (not shown) from the other end of said belt.
  • the apparatus of FIG. 9 is basically same in structure as the apparatus of FIG. 8 except that the back plate 92 of the branch 3 covers the upper end of the perforated endless belt 5 extending into the branch 3, a press roller 93 is fitted at the lower end of the front plate 83 of the branch 3 and an air shutter plate 91 having an adjustable length is provided inside said belt 5.
  • a back wall 94 is additionally provided under the back plate 92.
  • the air pressure in the space between the perforated endless belt and the front plate 83 of the branch 3 becomes larger than the air pressure in the space occupied by the backside of said belt, the back plate 92 of the branch 3 and the back wall 94. Accordingly, the air inside the duct passes through the part of the perforated endless belt 5 in the branch 3 more easily than in the apparatus of FIG. 8, and as a result the fiber material mixed in said air collects on the surface of the perforated endless belt 5 more easily and said collected fiber is formed into lap with the revolution of said belt in cooperation with the action of the press roller 93 and carried out to the other end of said belt.
  • the apparatus of FIG. 10 is characterized in that a direction control wing 101 for controlling the direction of the air stream carrying the fiber material flowing inside the duct 1 is provided in front of the upper end 5' of the perforated endless belt 5 extending into the branch 3 so that by controlling the angle of this direction control wing 101 the desired volume of the fiber material will collect on said belt.

  • FIGS. 8 and 9 already described and FIG. 11 described hereunder are same as the case of FIG. 10 in that the fiber material collects in the aforesaid triangular space of the vertical section.
  • the apparatus of FIG. 11 is substantially the same in structure as the apparatus of FIG. 8 except that a rotor having a plurality of wings 111 is provided in a location corresponding to that of the direction control wing 101 of the apparatus of FIG. 10 and the press roller 93 is provided at the lower end of the front plate 83 of the branch 3,

  • a plate 112 provided immediately above the upper end of the perforated endless belt 5 inside the duct 1 can have the end 112" moved up and down with the pivot 112' as a supporting point, thereby controlling the volume of air passing through the perforated part of said belt, thus controlling the density of
  • the delivering apparatuses of FIGS. 8-11 are, as mentioned above, so constituted that air inside the duct 1 flows against the front of the endless belt 5, so that the width of said endless belt 5 must naturally be made substantially the same as that of the carding cylinder. Therefore, in said apparatuses it is necessary to enlarge the width of the duct 1 to that extent as compared with the case as shown in FIGS. 17 wherein air inside the duct 1 flows laterally of the endess belt 5. Because of this, when these apparatuses are used, the space occupied by the duct 1 in a factory becomes large and an air blowing apparatus for forming an air stream inside the duct 1 is required to be enlarged in proportion, which is a shortcoming.

  • Said guide plate 142 may be omitted by placing the end of the dish plate 6 directly under the perforated roller 141.
  • the apparatus of FIG. is so constituted that the fiber material transfer means provided under the branch 3 is not perforated as in the apparatus so far explained, but is an endless belt 151 without perforations for passage of air.

  • the part of the member constituting the branch 3 in which said perforations are provided must be at least on the lower part of said member, and when the branch is short the perforations approach the upper opening of the branch, but what is important is that air in the branch flows out downwardly from the branch through the perforations.
  • a greater volume of air carrying the fiber material is caused to flow through a part of the collected fiber material where the density is thin, whereby the fiber material is gradually built up in said thin part, whereby it is possible to make the density of the fiber material in the branch 3 uniform in the same manner as in the aforesaid apparatuses.
  • An embodiment in which an auxiliary duct 61 is additionally provided is shown in FIG. 15, but the auxiliary duct 61 can be omitted.
  • the delivering apparatus of this invention which, as described above in detail, causes the fiber material coming out of a blowing machine to flow together with air inside a duct, causes at least a part of said air carrying the fiber material to flow into each of a plurality of branches provided at intervals along the duct and opening out of and extending downwardly from the duct, and causes said air to flow downwardly in each of said branches, thereby &

  • the apparatus of this invention makes uniform the distribution of the collected fiber material in each branch by causing the whole or a part of the air flowing into each branch to flow out downwardly therefrom, the distribution of the collected fiber material is made all the more uniform and therefore the height of each branch must inevitably be small as compared to that of existing tower hoppers, which results in the advantage for the present invention that it occupies a smaller space in a factory and is easier to operate.
  • the uniformly distributed fiber material collected in each branch as mentioned above is successively carried out of each branch while being formed into a uniform lap and is delivered onto the feeding end of each carding engine, for instance, the dish plate.
