For large scale production treadle operated automatic machine are very much necessary for speedy punching & eyeleting.
The machine has the following parts :-
EYELET CONTAINER:- Before starting the machine fill the eyelet container & when the machine is working, this container vibrates. And due to vibration & electromagnetic induction eyelets fill the guide channel one after another.
GUIDE CHANNEL :- It is used to guide the eyelet from the eyelet container to the material. The width of the guide is varying depending on the punching device & eyelet size. In some new development machine the width of channel is adjusted without changing the channel.
DICE & BRASS ANVIL:- Dice is used to punch the material & Brass Anvil is used for hammering work. There are different size of dice & anvil are available in the market.
WIDTH ADJUSTING DEVICE:- It is used to adjust the width between two eyelets, it is connected with the feed device.
TREADLE :- Treadle is connected with the feed device. The machine is operated on pneumatic pressure & it is also useful for inserting rivet buttons, grommet etc.
•Before starting the machine, oiling the machine regularly. Eyelet width should be the same as channel width & dice diameter should be matched with the eyelet. Before eyeleting in the upper component, it is recommended to adjust the width & Practice eyeleting on a wastage material.
EYELETS:- Eyelets are used to reinforce the holes for shoelaces & may serve as ornaments. An eyelet may also be used instead of a rivet to join the section. Eyelet should be rust-proof. Inferior qualities are brass plated but they are not durable. There is no standard form of eyelet numbering regarding their sizes.
