CHANGING THE HEAT PLATES
BOTTOM PLATE
TO REMOVE EXISTING BOTTOM PLATE
Swing head of machine to the side to give clear working access
to the bottom plate. Rotate the bottom plate anti-clockwise.
This in effect simply unscrews it and after several turns can
be lifted away.
TO INSTALL REPLACEMENT PLATE
Insert post of bottom platen into the receptacle on the
machine base. Rotate bottom platen clockwise until the
required pressure is achieved between the plates.
TOP PLATE
The top plate can only be changed by returning
the 3030 machine to J&A (International) Ltd.
HEAT SEALING BEST PRACTICE
Basically the heat seal procedure comprises three essential
elements of time, temperature and pressure.These elements need
varying for different fabrics, products etc. The tips and hints
below will help you to achieve perfect results every time.
DON'T FORGET THAT J&A WILL BE ONLY TOO HAPPY
TO GIVE ADVICE AND TEST FABRICS/GARMENTS FOR YOU
DIFFERENT TYPES OF BADGES/TRANSFERS
The correct heat seal parameters for each type of decoration
supplied by J&A (International) Ltd are given on the product
packaging and on the 'Heat Seal Parameters' chart available on
request from J&A. A version correct at time of printing is shown
on pages 6 & 7.
The parameters quoted above are guidelines which are
satisfactory for most fabrics but do please read the points below
and bear in mind they may occasionally dictate that parameters
are set outside usual ranges. J&A (International) Ltd accept no
liability for goods damaged by the heat sealing process.
DIFFERENT FABRIC TYPES
Differing fabrics require differing heat seal parameters to ensure
good adhesion of the decoration and prevent marking/damaging
the fabric/garment. J&A (International) Ltd have built up an
extensive data-base of optimum parameters for various fabrics
and will be pleased to advise and recommend settings.
FABRIC THICKNESS
Principally, the thicker the fabric, the longer the dwell time
required. There is no exact formula to determine the time
required - simply experiment with the particular fabric you are
using as to what dwell works best.
