I use one of these:
http://www.mdpsupplies.co.uk/applicationtaperoller.asp
At £40 it’s a no brainer.
I have two 8ft x 1m benches end to end with the roller in the middle (there is a flap on the roller that i trap between the benches to stop it moving). If you are limited with space you could use only one bench as the roller hooks over the end of the bench.
I lie the job on the bench and feed it under the roller and through onto the second bench. To ensure consistency I tape in lengths of under 2m – any longer and the tape can sag and drop onto the vinyl. I pull the tape out and firmly stick it to the bench, the apply the tape working towards the roller. Once i get about 30cm from the roller I can then unstick the tape from the bench and pull more of the job through. Simply repeat until the whole job is taped, then trim.
I have taped lengths of vinyl over 7m long without any creases or bubbles easily and consistently.
Thanks,
Owen
