Indian Standard SPECIFICATION FOR

FALLER BARS FOR JUTE DRAWING FRAMES

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 10 December 1985, after the draft finalized by the Jute Mill Accessories and Jute Machinery Spare Parts Sectional Committee had been approved by the Textile Division Council.

0.2 This standard has been published in order to provide guidance to the manufacturers. This would ensure the production of faller bars of acceptable quality and hence help in smooth functioning ofjute drawing frame and thus increasing its productivity.

0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard prescribes the requirements of failer bar screw gills for use in drawing frames in a jute mill.

2. MANUFACTURE

2.1 Material

2.1.1 Heads of the failer bars shall be made out of high carbon steel. Steel conforming to designation T 118 as per Schedule VI of IS : 1570- 196lt is suitable for this purpose.

2.1.2 Body of the faller bars shall be made out of steel conforming to designation 2OC8 of IS : 1570 ( Part 2 )-1379$.

*Rules for rounding off numerical values ( revised ). *Schedules for wrought steels for general engineering purposes. $Schedules for wrought steels:

( jir~t revision ). Part 2 Carbon steels ( unalloyed steel )

3

IS : 11508 - 1985

2.1.3 Gill pins shall conform to the requirements of IS : 4909-1968*.

2.2 Finish - Head shall be hardened, tempered and sand blasted and it shall be butt-welded at both ends with the body.

3. REQUIREMENTS

3.1 Pinning Requirements - The pinning requirements of the faller bars shall be subjected to the following tolerances:

Distance of first pin centre from end bar, mm f OS75

Width of gill between centres of last and first pin, mm & 0.75

Length of pins projecting outside the bar, mm f 0.50

Distance between two consecutive gills centre of nearest f 0.75 pins, mm

Pitch of pins, mm f 0.15

Distance between two rows of pins, mm rt 0.75

3.2 Dimensional Requirements

3.2.1 Nominal - The nominal dimensions of the faller bar shall be as agreed to b.etween the manufacturer and the purchaser or in the absence of any agreement, the nominal dimensions would be as declared by the manufacturer.

3.2.2 Tolerance - The dimensional requirements of faller bars ( see Fig. 1 ) shall be subjected to following tolerances:

Overall length (A), mm + 0.10 - 0.20

Faller body width (B), mm f 0.05

Faller head width (C), mm f 0.20

Overall thickness (D), mm f 0.20

Thickness at check spring slot (E), mm f 0.075

Width of check spring slot (F), mm f 0.075

End dimensions, mm * 0.50

Faller head angle ($), minute O”- 15’.0”

Distance between check spring slot (G), mm f 0.50

*Specification for card and gill pins for use in jute industry.

4

IS : 11508 - 1985

3.3 Hardness - Failer bars head shall have hardness of 58 to 62 HRC with a minimum case depth of 1 mm.

3.3.1 Hardness shall be determined as per IS : 1586-1968*.

3.3.2 Case depth shall be determined as per IS : 6416-1971t.

3.4 S&face Flatness - The maximum deviation in the flatness of the bar when measured with a filler gauge on a smooth flat surface shall not exceed 0’30 mm.

4. MARKING

4.1 Unless otherwise agreed between the buyer and manufacturer each failer bar shall be legibly marked with the manufacturer’s name or trade-mark.

4.2 IS1 Certification Marking - Faller bars may also be marked with the IS1 Certification Mark.

NOTE -The use of the IS1 Certification Mark is governed by the provisions of the Indian Standards Institution ( Certification Marks ) Act and Rules and Regulations made thereunder. The IS1 Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by ISI and operated by the producer. IS1 marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a licence for the useof the ISI Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.

5. SAMPLING AND CRITERIA FOR CONFORMITY

5.1 Lot --.In a consignment, all the failer bars manufactured under the same condition shall constitute a lot.

5.1.X For conformance of this specification, the sample shall be drawn from the lot and it shall be in accordance with Table 1.

5.2 Number of Tests

5.2.1 All the faller bars in the lot shall be visually examined for workmanship and finish. For requirements given in 3.1, 3.2 and 3.4 tests shall be conducted on the samples selected in co1 2 of Table 1.

5.2.2 For requirements of 3.3, sub-sample as given in co1 4 of Table 1 shall be selected from the samples already selected and each failer bar in the sub-sample shall be tested.

*Method of rockwell hardness test ( B & C scales ) for steel (firrf revision ), ?Methods for measuring case depth of steel.
