Device to be applied on circular knitting machines for making stocking elements with
stretched cuffs and adapted for locking the cuff and reversing the stocking elements
being formed |
(57) The invention relates to a device to be applied to a circular knitting machine for
making tubular elements with stretched cuffs or top edges to be used for making stocking
articles. The device comprises a stem traversing a longitudinal cavity formed in the
circular knitting machine plate supporting shaft, the shaft being rotatably coupled
to the stem which may swing axially and the end of which projects under the machine
plate and bears a rigid member provided with an annular edge which, between the two
end of stroke positions of the stem, may be held removed from the plate lower face
and held pressed thereon, so as to define a hollow chamber for holding the cuff between
the plate and rigid member within the annular edge. The stem is coupled to a cam supported
by the knitting machine cam main drum, in such a way as to hold the rigid element
lowered at least during the first cuff making step and at the end of the forming of
the tubular element and to hold that same rigid element raised during the intermediate
steps. Thus, the just formed cuff is locked on the machine plate and the tubular element
is reversed during the making thereof to be completely reversed at the end of the
making step thereof.
