Objective of Loose reed motion l Structure and working of loose reed motion(warp protector motion)

Loose reed motion ( warp protector motion):
Objective of loose reed motion:
When a shuttle loom works, there is always a chance to trape the shuttle in the shed. Since the reed performs beating motion, the shuttle gets beaten by the reed in case of shuttle trapped situation. the beating of the shuttle after trapping is a very serious problem during weaving. Multiple warp breakages get occurred in this situation. The shuttle and reed may be damaged. The loose reed motion mechanism prevents multiple warp breakages, damage to the reed and shuttle.
In this way, we can say that the main objective of the loose reed motion mechanism is to prevent the multiple breakages of warp and damage of shuttle and reed.
Structure of loose reed motion:
Reed is mounted in the reed case and reed cap. The reed cover arm helps to hold the reed firmly. This reed cover arm looks in L shape. It gets fulcrummed near the joint of the dagger or stop rod finger. An anti-friction bowl is also connected with a stop rod. The anti-friction bowl presses the bow spring in normal running condition. A spiral spring is also connected with the stop rod. A frog is attached to the stop rod. A heater is mounted on the starting handle in such a way that that frog passes under it in normal running conditions. A serrated bracket is mounted on the starting handle. The dagger does not push this serrated bracket in normal working.
