The movable part of the machine, the travelling carnage,contains the spindles, spindle cylinder, winding mechanism,and, in the central piece, the rest of the driving gear. The length of the machine, which depends on the numberand setting of the spindles, is usually adapted to the dimen-sions of the available space, and is generally 60 to 80 the Josephy mule (Fig. 238) the length is calculated bythe formula h = n t + 1700 m. (6y in.), wherein « equals thenumber of spindles and / equals the distance, between centres,of two adjoining spindles. In order to economise space and lighten the attendance onthe machines, the headstocks are generally set alternately at.

The depth of the frame is determined by the carriagetraverse, and varies from 5 J, ft. to 8 ft.
