Butt Splicers

A Martin butt splicer is serious automation for many web-fed processes. A butt splice joins two webs together–typically, the end of an expiring roll to the beginning of another. The two ends are trimmed straight and brought together so that the ends do not overlap. A thin tape, over the top or bottom of the splice, or both, holds the splice together. This splice method is required in applications…

Lap Splicers

A taped overlap, or “lap,” splice joins the end of an expiring roll to the beginning of another. The two webs are brought together, one over the top of the other, with a thin adhesive tape between the two. A short length of web, or “tail,” results when the expiring web is cut. A Martin Automatic lap splicer performs this splicing function without slowing or stopping the process…

Heatseal Splicers

A heatseal splice joins the end of an expiring roll to the beginning of another without the need for adhesive. The webs must be thermo-bondable, or able to bond together when heated. In a heatseal overlap splice, the two webs are brought together, one over the top of the other. The webs are clamped between heating elements, causing the material to fuse together…

Automatic Rewinds and Turret Rewinds

Martin offers a range of rewinds that automatically transfer the running web from a full roll to an empty core without stopping or slowing the line. From the LR and LRD winders, which automatically unload finished rolls; to the versatile RMAP, capable of winding rolls of film, paper, nonwovens and paperboard; to the TR shaftless or shafted turret rewind, Martin rewinds feature many performance…

Tension Control Systems

Web tension upsets between a roll and the process may be caused by braking of the running roll, splicing action, acceleration of the new roll after splicing, and out-of-roundness or imbalance in the roll. A dancer system using the principle of inertia compensation effectively absorbs tension upsets and delivers constant web tension to the process. Inertia compensation is achieved…

Decurlers

A web may need to be decurled for two reasons: one, to remove curl that has been wound into the roll (sometimes called “roll set”); or two, to remove curl that has been caused or magnified by the process. Martin makes two kinds of decurlers: pre-press (or pre-process) and post-press. A pre-press decurler is located before the printing units and is intended to help remove roll set…
