In this
way one or more layers of the fleece can be placed on the sheet, which
in that case passes backwards and forwards from roller S to R, and _vice
versa_. It is, in fact, the bat arrangement used for felt, only with
this difference, that the bat is at once rolled up instead of going
through the bat frame. In the manufacture of felt it is of course of
importance to have many very thin layers of fleece superposed over
each other in order to equalize it, and if the same is applied to the
manufacture of cloth it will no doubt give satisfactory results, but may
be rather costly.

NOVELTIES IN RING SPINDLES.
One of the drawbacks of ring spinning is the uneven pull of the
traveler, which is the more difficult to counteract as it is exerted
in jerks at irregular intervals. It is argued that with spindles and
bearings as usually made the spindle is supported firmly in its bearing,
and cannot give in case of such a lateral pull when exerted through the
yarn by the traveler, and the consequence is either a breakage of the
yarn or an uneven thread. Impressed with this idea, and in order to
remedy this defect, an eminent Swiss firm has hit upon the notion of
driving the spindle by friction, and to make it more or less loose in
the bearings, so that in case of an extra pull by the traveler the
spindle can give way a little, and thus prevent the breakage of the
yarn.
