ENTUBADO BUNCH:
This technique rolls each filler leaf into itself like a scroll. Each scrolled leaf then is placed together with other scrolled filler-leaves. Employing this pain-staking tact creates dense cigars with excellent air-flow, therefore draws. Such a challenging task, is Entubado, that it is rarely if ever used in large runs.
Involves folding a single side of the filler leaf inward from a singular direction, then placing it atop another and so forth, so-on. The folds allows excellent air-flow and therefore draw. Accordion is surpassed only by Entubado in terms of difficulty and result. Dissection of fillers would display as bellows.
BOOK BUNCH:
Involves piling filler leaves flatly, one atop another, then folding them up as name implies. The advantage is faster and easier manufacturing. However, this method can yield a potential lack of air-flow as the flattened tobacco can be quite compressed. Still, this is the most popular technique in cigars to-day.
A technique which involves placing binder/filler leaves on a canvas which rolls 'em up so's you don't have to. Since human hands assist in feeding the machine's mechanical brain and/or appendages, the resulting offerings are still deemed premium products. The difference twixt the legalese of "Hand-made" and "Hand-rolled."
CUBAN SANDWICH:
[honorary mention]
"One mixed-filler method, the Cuban Sandwich approach to manufacture, sees short-filler rolled into long-filler leaves. Ah, the art of the $2 stogie." Me (earlier to-day) in: The Long & Short of Long, Short, & Mixed Fillers, A Cigar Primer.
