LOOM

MR. JANMAY SINGH HADA

2. A loom is a device used
to weave cloth.
The basic purpose of any loom is to
hold the warp threads under tension
to facilitate the interweaving of the
weft threads.

MOTIONS OF LOOM
In order to interlace warp
and weft threads to produce
a fabric, the following
motion are necessary on any
type of loom:

5. To get high productivity and good
quality of fabric, additional
mechanisms, called auxiliary
mechanisms, are added to a loom.
The auxiliary mechanisms are useful
but not absolutely essential.

AUXILIARY MOTIONS

7. Warp stop motion stop the loom when a drop
wire fall as the result of end break.
The broken end is repaired and handled by the
operator.
WARP STOP MOTION

8. This motion enables
to stop the loom
immediately after a
weft break or weft
running out.
In case the loom is
allowed to run even
after the weft breaks
there will be no
woven cloth except
long threads of warp.
WEFT STOP MOTION

9. If shuttle fails to
reach its proper box,
a loom must either
be instantly stopped
by a fast reed
motion or gradually
stopped by loose
reed motion.
WARP PROTECTOR MECHANISM

10. It will stop the loom to
prevent excessive
damage to the warp
threads, cloth, and reed
if the weft carrier
becomes trapped
between the top and
bottom of the shed lines
and the reed.
WARP PROTECTOR MECHANISM

11. It ensures a continuous supply of weft
yarn to the loom whenever supply
package exhausted.
WEFT REPLENISHMENT

12. A brake is a device by means of which
artificial frictional resistance is applied to
moving body in order to stop the motion of a
loom.
The brake stops the loom immediately
whenever required. The weaver uses it to stop
the loom to repair broken ends and picks.
Types of Brake –
•Shoe Brake
•Band Brake
BRAKE

13. The temples are used to hold fast the width of the woven cloth
as equal to as possible to the width of the warp.
It may be made of wood or metal.
Metal is useful for rugs.
TEMPLES

14. Ring
Temple
Roller
Temple
TYPES OF TEMPLES

15. The narrow edge of woven
fabric that runs parallel to
the warp.
Created by the weft thread
looping back at the end of
each row.
SELVEDGE

16. It is made with stronger yarns in a tighter construction
than the body of the fabric to prevent raveling.
