1. General
The operating principle of the PK5000 load carrier isbased on a pneumatic load on the 3 top rolls.
The PK5000 load carrier is suitable for staple fibres
up to 60 mm.
+ F3300
The pressures from the load on the 3 top rolls isadjusted centrally and continuously via a pneumatic
regulating system. This ensures even pressure app-
lied at all spinning points.
The PK5000 load carrier offers the possibility of acentral partial relief.
The PK5000 load carrier comprises:
1 = Support2 = Carrier 3 = Operating knob
4 = Weighting element top delivery roll
5 = Weighting element top cradle roll6 = Weighting element top feed roll
7 = Top delivery roll

3. Top rolls
The following parts are used in the PK5025 andPK5035 load carriers:
The top roll shafts are type LP 315.
The top roll shaft LP 317 is used only for the cradlelong.
The maximum rated load on the top roll shaft is 35kg.
Top roll cots with PRESS-FIT.
3.1 Lubricants for re-lubricating the top roll ball bearings
The top roll ball bearings are lubricated in the factorywith Staburags NBU 12/300 made by Klber Lu-
brification Munich.
Alternatives:
Complex soap grease
Worked penetration: approx. 300 mm / 10 at 25C
Drop point: >200C
Useful temperature range: -20C to +120Ce.g. SKF grease TG5-26878
Calcium-saponified roller-bearing grease
Worked penetration: approx. 265 mm / 10 at 25C
Drop point: >190CUseful temperature range: -30C to +60C
The top roller ball bearings require re-lubrication with1 pump stroke after 30,000 hours.

3.2 Regrinding top roll cots
The top roll cots of the cradle rolls must never be
reground.
When regrinding the top roll cots of the feed and
delivery rolls, respect the minimum = 31 mm.
The grinding interval depends on the degree of rub-
ber hardness and the material being processed:
Delivery rolls = 2,000 to 4,500 hoursFeed rolls = 4,000 to 9,000 hours
4. Spacers
Key:
1 = Cradle
2 = Spacer 3 = Guide bar
X = Cradle aperture (thickness)
To ensure good roving quality it is advisable to keepthe gap small between the top delivery roll and the
top apron.Make sure that the delivery condenser can move
freely (at least 1 mm play).
The cradle aperture X also affects the quality of
the roving.
Result of a small cradle aperture X:Better Uster values on the roving frame but
worse working behaviour on the roving frame- draft-associated problems (sliver piecer)- more slubs and snicks (thick and thin spots)
- greater susceptibility to fluctuations intemperature and blends
Hence more downtimes for the machine.
Result of a somewhat larger cradle aperture X:
Uster values on the roving frame are 0.2 0.4%worse but
good working behaviour on the roving frame
good working behaviour on the ring-spinning
machine
up to 30% fewer end-breaks no measurable difference in the Uster value of the
yarn
better IPI values in the yarn.

5. Condenser

the quality of the roving and the working behaviourof the roving framer.

rent, depending on the material being processed.

11. Manual strength test of roving
The manual testis conducted as follows:
1. Stand a full roving package (1) on end on a hard
table top (2).
2. Take hold of the roving with your fingers at (3)
and slowly pull (taking 12 to 18 sec) in the directi-
on of (4). The tensile force of the roving will make
the bobbin slowly turn.3. When the roving breaks between 3 and 4 the di-
stance measured between 3 and 4 indicates the
tensile strength of the roving. Perform at least 5
tests and calculate the average.
Dis tance 3 to 4 Assessment:
300 to 500 mm = soft roving twist
500 to 800 mm = norma roving twist
800 to 1100 mm = hard roving twist
over 1100 mm = roving twist is too hard,
cannot be drawn on the
ring-spinning frame.

The drafting system(1) refines the roving drawn infrom the roving bobbin until it reaches its final count.
The fibre fleece leaving the bottom delivery roller /
Suction drum (2) is rapidly twisted into a thread. Thetwist in the thread is evenly distributed by means of
the spindle and the ring traveller. The thread goes
from the bottom delivery roller / Suction drum (2) tothe ring traveller and the spinning tube, which toge-
ther with the spindle (9) forms a single unit, and iswound around the spinning tube.
In the event of an end-break the fibres leaving thebottom delivery roller / Suction drum (2) are caught
by the suction tubes (3) and collected in the suctionunit.
The 4 spindle tape drive (11) ensures quiet, energy-
saving operation.

4. Draft Height
4.1. Draft Height dependent on staple length
With the two-apron drafting systems it is possible toachieve optimal results with regard to yarn uneven-
ness as well as highest draft values. Compared with
other systems, our two-apron design is notably
trouble-free. There is a particularly wide draft range
(from 12 to 80) within which good Uster values areachieved. This
does not mean, however, that optimal values can
always be guaranteed with any material and any
draft. It is essential that the optimal spinning condi-tions be established.

Broken ends must also be taken into account. Neit-her the Uster values nor the breaking strength of the
single yarn are decisive factors on their own. Other
important factors are the staple, preparation and
roving twist, especially the height of the total draft and
its distribution, the setting of the break draft zone, thethickness of the spacers between nose bar and
cradle, and the grade of rubber used for the upper
delivery rollers.
Apart from these drafting aspects, end breaks may
also be significantly affected by other spinning para-
meters, such as ring diameter and section, traveller
number and type, tube length and diameter, andabove all spindle speed. These parameters, how-
ever, cannot be addressed in greater detail in the
present instructions.
In principle, to obtain good end break rates with
cotton, the total draft should lie roughly inside the
limits shown in the table opposite.
These limits must not be confused with those foroptimal Uster values, which must always be deter-
mined by trials, as they are strongly influenced by
other factors, particularly the material being spun.
Naturally, the table opposite is intended only as a
guideline.
The maximum draft possible, however, depends on
the material being processed.
When determining the daft on the ring-spinning fra-
me, the draft on the roving frame must also be takenin account, especially the minimum draft.
There are also limits on maximum weight allowedat feed on the roving frame:
Cotton max. Ne 0.10 Blends (cotton/poly) max. 0.115 100% Synthetic fibres max. 0.12
