  • Figure shows that the sliver runs from the can via a trumpet into the feed shoe {m}.
  •  A fluted feed roller {s} is designed to clamp the sliver evenly over its whole width & to move it forward slowly into the operating region of the opening roller{a}.
  •  The feed roller generally has diagonal fluting in order to increase the clamping effect.
  • In some brands of machine, it is necessary to adopt the feed shoe to the material because it is important that the fibre beard is presented to the opening roller in an optimal manner.

  • In this case, the form of the feed shoe & the opening roller must be changed. The distance between the feed shoe & the opening roller must be changed.

  • The distance must be decreased for finer feed sliver or smoother fibres or both.

  • If the yarn breaks , feed of material into the machine ceases immediately.

  • This is done by stopping rotation of the feed roller or by pivoting the feed trumpet so that the sliver can not run through the shoe.
