The STERLING® COILMASTER JR. TS is an automatic, table top plastic coil binding machine. It inserts plastic coil from the first hole onwards, then cuts and crimps. This tabletop unit is affordable and can bind books from 8 mm to 25 mm. Speeds of up to 600 books per hour can be attained.
This plastic coil binder can bind books of any pitch, with round or oval holes. The margins can be slim or wide, up to 3/8”/9.5mm, meaning that you can pull punch pins prior to punching, and center the sheet. It can bind books of any length between 4.5”/114mm and 12”/305mm- not just a few standard sizes.
The criss-cross combs guide the coil from both the front and the rear ensuring stable coil insertion. The crimping knives create a ninety degree crimp.
You would think that 4:1 means four holes per inch. That’s not always the case. Most 4:1 dies are .248 or .2475 pitch rather .250 or a true 4:1. This allows for punching a hole pattern meant for 8.5 X 11 or A4. You can fit 44 holes on these size books without pulling pins.
But what if your book isn’t exactly 11” or A4? You will end up punching half a hole. The best solution is to pull the punching pins at the head and foot of the book, and center the sheet to make an attractive margin.
Thanks to the spreading device on The Coilmaster Jr. TS, you can pull pins and center your sheet, regardless of the length of the book or the pitch. Here we have a true 4:1 pitch, four holes per inch, with a wide and extra wide margin, much wider than the distance between the holes.
