Abstract
A roving moving to a spinning machine passes between top and bottom input rolls of which the top roll is adapted, upon breakage of the roving, to be raised by a lift member which is movable into engagement with the spindle of the top roll and carries with it a clamping element which serves to clamp the incoming broken end of the roving against the top roll to retain it ready for subsequent rethreading into the nip of subsequent drafting rollers.

In a spinning machine, a drafting frame comprising an input roll pair including:
- a bottom roll,
- a top roll mounted above and cooperating with said bottom roll,
- a spindle forming part of said top roll,
- mounting means permitting said top roll to be lifted from said bottom roll in the event of yarn breakage;
- and
- engagement means adapted for lifting said top roll upon yarn breakage and including
- a lift element mounted for movement into lifting engagement with said spindle, and
- means defining a clamping element carried by said lift element and movable by said movement of said lift element into lifting engagement with said spindle for engaging roving passing between said input roll pair and clamping the leading end of said roving against said top roll.
In a spinning machine, a drafting frame comprising input roll means including:
- a bottom roll,
- twin top rolls mounted above and cooperating with said bottom roll,
- spindle means forming parts of said top rolls,
- mounting means permitting said top rolls to be lifted from said bottom roll in the event of yarn breakage;
- and
- engagement means adapted for lifting said top roll upon yarn breakage and including
- a lift element means mounted for movement into lifting engagement with said spindle means of said top rolls, and
- clamping means carried by said lift element and movable by said movement of said lift element into lifting engagement with said spindle means for engaging roving passing between said top and bottom rolls of said input roll means and clamping the leading end of said roving.
