Existing compression unit disadvantageously, the wear parts with wearing face is positioned at drawing-off On roller.This just requires that the making of two wear parts must be very accurate, the most corresponding to guarantee Two bearing-surfaces arched upward in the circumference of draw roll can fit tightly with described draw roll.Have In the case of necessity, it is necessary to they are fitted and regulate, to ensure at wear parts and to lead Stretching and do not produce the big gap being not allowed between roller, the fiber of ribbon can enter this big gap In.

Therefore, the task of the present invention is to provide a kind of compression unit, this compression unit manufacturing cost Low, and ribbon that is in draw roll and that guided by compression unit and compress can be pointed to It is compressed like clockwork.

Summary of the invention

According to an aspect of the present invention, the compression of the drafter for spinning machine provided Equipment has the pressure channel of at least one ribbon for completing drawing-off.Described complete drawing-off Ribbon directed into this compression unit by the drafter before being positioned at compression unit.Described pressure Contracting unit has support and at least two wear parts.Said two wear parts is preferred with support Firmly it is connected, but they can also be movably mounted on support.At least one wear parts It is provided with the bearing-surface of draw roll.Described compression unit is by the second wear parts and in draw roll Bearing-surface obtain support.When described wear parts is the most rack-mount so that it is leading Stretch and be spaced apart from each other on the circumferencial direction of roller.First wear parts has at least one and guides fiber The upper spigot surface of bar, and the second wear parts has the pressure channel of ribbon.First wear-resisting portion Part first directs into ribbon in draw roll, then routes it to the wear-resisting portion of second subsequently Part.Second wear parts compresses this ribbon by its pressure channel, the most so By ribbon tight compression, i.e. ribbon is guided into the side of pressure channel, is then pressed in pressure On the sidewall of contracting passage.After compression such to ribbon, next just can produce the most excellent The line of matter, such as, use ring throstle to produce.

According to the present invention, the upper spigot surface of the first wear parts is wear-resisting pin, at one preferably Embodiment in, this wear-resisting pin can from above to ribbon pressurization guide, and Do not contact draw roll.So there is no need to make must accurately be arranged on around the second wear parts to lead Stretch on roller.This set can be realized by adjustable component or by wear parts, thus handle First wear parts takes the tram guiding ribbon to.Rack-mount first is wear-resisting Parts are pressed onto ribbon draw roll from above.During by the first wear parts, ribbon exists Compressed between this parts and draw roll.Define thin between the first wear parts and draw roll Little opening, ribbon through this opening and is compressed for the first time.The most higher to ribbon The second time compression of strength is to be completed by the second wear parts being provided with pressure channel, in this compression In passage, ribbon is compressed the most strong.

Due to the first wear parts and be not positioned immediately in draw roll, then require institute the most at once Stating wear parts draw roll to be coordinated, the manufacturing cost of the most whole compression unit just can be significantly Degree declines, and ribbon can be carried out accurate compression simultaneously.

In an advantageous embodiment of the present invention, described compression unit has two first With the second wear parts, for two ribbons run side by side.So unique compression unit May be used for two parallel drafters and spinning apparatus, cost reduces further.
