Claims
- 1. A method of unrolling and piecing a lap for combing machines, lap drafters and the like, comprising the steps of:
- supporting the lap on a pair of rolls, at least one of said rolls being connected to a drive which can be selectively engaged and disengaged;
- disengaging said drive to said one roll to render said roll freely rotatable whereby a fiber layer of the lap can be easily unrolled therefrom;
- piecing the fiber layer of said lap to a fiber layer of another lap; and
- thereafter engaging said drive to said roll, whereby the lap is thus driven and the fiber layer is therefore unrolled from said lap without being drafted.
- 2. A method of piecing laps in a textile machine fed by an operator with heavy laps and having a lap drive comprising a pair of support rolls for supporting a lap which is to be unrolled for processing a drive for at least one of the support rolls, the drive being normally coupled to said one support roll to rotate it to unroll a lap supported thereon, said method comprising the steps of:
- uncoupling said drive so that both rolls can rotate freely to permit manual unrolling of a length of fiber layer from a heavy lap supported by said rolls; and
- piecing said length of fiber layer to the end of a lap already being processed.
- 3. The method as defined in claim 2, wherein:
- both said rolls are driven and both are uncoupled for piecing.
