What is a butt splice?
A Butt Splice is a "join" made between 2 webs in which the trailing edge of one web is "butted" to the leading edge of a second web.
Why butt splice instead of lap splice?
- A 2 ply material needs to be separated downstream in the converting process. Therefore, the materials must be butt spliced, with one piece of tape holding each ply.
- A material is too thick when overlapped to make it through the various operations of the converting process.
CTC offers a comprehensive range of standard and application engineered butt splicers to meet a variety of non-stop production requirements.
Some of the industries using CTC Butt Splicers include:
Label and printing, Carton, Nonwovens
1. Shaftless Turreting Butt Splicers
Commonly found in the Label Printing industry, models are currently available in web widths up to 24".
A 2 sided tape butt Splice of pressure sensitive label stock
2. Cantilevered Turreting Butt Splicers
These models are used in a variety of applications. Currently available to accommodate roll O.D.'s of 42" or 62". Web Widths of 10" and 16" are available.
3. Cantilevered fixed Spindle Butt Splicers
These models are used in a variety of converting applications and can be custom engineered to the precise roll diameter, web width, web tension and line speed required.
4. Heat Seal "Tapeless" Butt Splicers.
These Models are always fixed spindle and typically of cantilevered construction. They can be provided free standing, or plate Mounted and ready for Integration into a Converting Line. They are typically found in the nonwovens or plastics industry where thermoplastic materials are used.
5. Narrow Web Fixed Spindle "Same Side" Butt Splicers.
These models use a unique splice mechanism that always places the splicing tape on the same side of the web without having to turret the unwind spindles . They can be used in applications such as providing butt splicing for label applicators, where the splicing tape must always be on the liner side.
