Splice Mechanism

The Butt Splicer mechanism employs a flying knife which moves across the web as it makes a cut. The CTC design produces the most accurate and consistent zero gap butt splice of any machine on the market., and is the most user friendly in terms of splice preparation. It also has a unique feature which applies tape to both sides of the web at the same location in the splice mechanism thereby significantly reducing the probability of the splice separating in the splicer. For those applications which only require splicing tape to be placed on one side of the web, the CTC Butt Splicing mechanisms have a unique advantage over competitive equipment because our splicers allow the splicing tape to be placed on the same side of the web each time the unit makes a splice. This design eliminates the need to have a turreting type unwind stand in order to achieve the same result.

Due to the wide range of materials which a butt splicer may be required to handle, CTC Butt Splicers are available with three different tension control systems. All three types employ our proprietary concept of using the festoon as a dual function element which acts as a dancer and as a web accumulator. Our precision balanced festoon/dancer rollers provide the most accurate web tension available on any splicer. The three tension control systems available are:

• 1. Pneumatic brakes with electronic integrator converting electronic signal from potentionometer to air pressure regulation. Note: For printing press applications, our is the most accurate tension control system for use with or without a supplemental press infeed system.

Splicing a printed web in register is accomplished by using a photoelectric cell (or fiber optics) to sense a printed eye mark. This signal is fed into the splicer logic control which delays the splice sequence until the pattern of the running web is in correct position to align with the pattern on the new roll waiting to be spliced in.

Features:

• Space saving, reduced overall dimensions
