Stretching the rubber while pasting

Hello Sir,

I am Ganesh from India. I usually use the vulcanizing glue for pasting my rubbers. I would like to know if there will be a visible effect if i stretch the rubber while pasting? I accidentally stretched the rubber last time while pasting. I still haven't played with it, but i already started worrying if this will create a sort of tensor effect on the rubber or shorten the life of rubber.

Also i fear if it will impart more of catapult effect and make it uncontrollable.

I am just wondering if this is also a means of making a normal rubber working as tensor rubber?

Your inputs highly appreciated.

Thanks Ganesh
