Description
Technical field
The present invention relates to a kind of weaving device, particularly relate to a kind of bifilar doubling device.
Background technology
Conically shaped yarn has easily unwinding, is difficult to the plurality of advantages such as off-clip, and in whole spinning technological process, conically shaped yarn is indispensable yarn type of organization, and due to the needs of next procedure, many operations often require that making conically shaped yarn.
Two strands of single thread generally can be merged one folded yarn of formation (non-twist plying) by doubling frame, during plying, typically the most important problem is to control the tension force that two one threads keep identical when plying, such two strands of single thread do not have long short-line problem when forming one, if there is long short-line problem, folded yarn is at the double twisting stage easy broken yarn in lower road, also upper appearance of twisting thread " little tail " is easily occurred in, it is thus desirable to strictly control the unwinding tension of two yarns, it is ensured that two strands of single thread keep length consistent when plying.
Further, doubling problem is encountered that when two cylinder yarns unwind plying at the same time, owing to the leftover yarn two of two cylinder yarn reel dresses is the most identical, particularly a cylinder yarn residue seldom (yarn wound packages diameter is less), another yarn residue is a lot (yarn wound packages is relatively large in diameter), one meter of yarn of same unwinding, the cylinder yarn that yarn wound packages diameter is less needs the cylinder yarn that the number of turns of unwinding is relatively large in diameter far more than yarn wound packages, further, in yarn unit unwound length, the number of turns moon of unwinding is many, and the unwinding tension reached the standard grade is the biggest.During the cylinder yarn doubling the most not of uniform size, the factor varied in size due to cylinder yarn causes and the problem of line mass needs to eliminate.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that the bifilar doubling device of a kind of simple in construction.
