Detailed Product Description
Vertical holing machine is a kind of machine tool which is applied to grind and polish the inside
M4220C vertical holing machine is a kind of machine tool which is applied to
grind and polish the inside surface of cylinders, tubes etc. It can grind one
or more than one according to different specifications. The
diameter of workpiece can be 30mm to 1,000mm and length up to 5m.
Our holing/sealing/capping machine is suitable for opening the hole in the head of plastic
ic laminated tube which is hermetic, and sealing the hole with
aluminum foil, then capping the tube finally. It includes three functions together.
This holing/sealing/capping machine is an ideal machine for the tube manufacture plants.
It uses the advanc
ed PLC control and screen
touch interface programs, and the servo
electric drive can keeps pinpoint. It also enjoys firm structure, widely usage, high speed
and stable operation. Accurate holing, attractive sealing and precise capping are all the
s of the machine.

PATTERN MAKING TOOLS
When fashion designers, patternmaking designers, or
pattern makers, ......, produce their draping design, or alter the
patterns and garments, the professional pattern making tools are needed:
Pattern Design Ruler
24” rulers that is shaped into a curve at one end. Used to curve hiplines on s
kirts and pants for drawing curved
hems, hips and other slightly curved areas.
Shaped a curve at one end, individual curves are used to shape armholes, necklines, sleeve caps, darts, crotch
seams, lapels, pockets and collars.
With one side longer than the other, shaped like the letter “L”, used to draft slopers and patterns to establish length
and grainlines on patterns and slopers.
4. Straight Ruler
To straight edge with clearly marked measurements rulers (12”, 18”, 24”)
A narrow, firmly 60” tape with metal tips on each end.
A hand punching tool which provide a 1/16” x 1/4” nick in pattern paper. Used to establish matching
on the outer edges of pattern pieces.
It also cuts through tag board.
A small hand tool with metal point, used to transfer markings from pattern onto fabric with or without tracing paper.
A pointed tool with a wooden handle. Used to pierce small holes such as to indicate a
Cloth weights are used to weight down pattern pieces or fabric pieces.
A pattern punch is used to cut a circular 3/4” hole on pattern papers to enable hanging up by pattern hooks.
Pattern hooks with cord are
used to properly hang patterns.
Cutting is extremely important in patternmaking and sewing. Without good cut, the sloper is doomed, so, with a pair
of professional heavy duty pattern shears(12”) that have an extra long shank and heavy blad
es is very helpful for
Indursty heavy duty fabric scissors: 8”, 10”, 12”, with extreamly sharp blades, good for cutting fabric.
A size 17 steel satin straight pin. Used to fasten parts and pieces together.
Professional draping tape, 3/32” width, 49 feet length, with 5 different colors to select. Very easy to curve and line
How do you clean and oil the sewing machine?
Things You'll Need
Manual for your sewing machine
Can of compressed air
Unplug your sewing machine.
Unscrew and remove the needle and foot and put them in a safe place.
Remove the throat plate on your sewing machine. Unscrew it if necessary and use the
roat plate lever to raise the plate so you can remove it. Your machine's manual should
have specific instructions for this.
Use tweezers and a lint brush to remove all bits of thread, debris or dust in the sewing
Carefully blow out the foot pl
ate and bobbin area with compressed air. Do not blow any
debris further into the sewing machine because this could cause problems later.
Place a tiny drop of sewing machine oil in each of the oil spots on your sewing machine.
Your manual will show you
exactly where these are located, or they will be marked on
Turn the hand wheel several times to distribute the oil.
Replace the foot plate and press the lever downward to lower it back into place. Replace
any screws that you removed.
place the sewing machine foot and needle.
Sew for a minute or so with a piece of paper towel or a scrap piece of fabric to absorb
excess oil. You do not need to thread the machine for this.

frequently employs one of
three pattern creation methods. The flat
begins with the creation of a
, a basic pattern for a fitted,
, made to the wearer's measurements. The sloper is usually made of
or style details. Once the shape of the sloper
has been refined by making a series of mock
up garments called
(US), the final
sloper can be used in turn to create patterns
for many styles of garments with varying necklines, sleeves,
dart placements, and so on.
Although it is also used for womenswear, the drafting method is more commonly employed in menswear
and involves drafting a pattern directly onto pattern paper using a
variety of straightedges and curves.
Since menswear rarely involves
making is the primary preparation for creating
sew woven garment. The initial measurements and adjustments are created on paper as a draft. More
paper is placed over top of the draft and traced off with seam allowance added to these pieces, which will
then be cut out and used to cut out actua
l fabric for sewing. If this draft will be frequently used, a sloper is
created to speed up the production time. A pattern maker would use various tools such as a notcher, drill
and awl to mark the pattern in places.
The pattern draping method is used for
more elaborate and unique designs that are hard to obtain
through the flat pattern method. This is because it is nearly impossible to account for the way a fabric will
drape or hang on the body without an actual 3
dimensional test run. It involves creating
a muslin mock
pattern by pinning fabric directly on a
, then transferring the muslin outline and markings onto a
paper pattern or using the muslin as the pattern itself.
Pattern grading is an essential part of pattern making. It decides how patterns increase or decrease
According to countries, pattern grading includes USA's, EUR's, UK's, and CHN's. Generally, pattern
grading adjusts for people of different ages and genders. The fabric type also influences the pattern
And marker makings are the actual full size print out of how the styles are cut on the
fabric. The cost of pattern grading is incomplete without considering marker making.

There are a number of different types of seams that have been developed over the years to do
erent jobs. While many have largely been superseded by the development of machine
stitches that finish as you sew them, and by the development of the overlocker (or 'serger' in
some parts of the world), it is useful to know some of the basic seams types an
d finishes. A lack
of expensive machinery need not prevent you sewing the garments you want. Also, some of the
older methods have never been bettered.
Here I am concentrating on machine sewn seams
using a standard straight stitch machine.
When you have ch
osen your fabric and pattern, you need to think about the most suitable way
to sew the garment together. This will depend partly on the type of fabric, partly on the use the
garment will get, and partly on the finish you want.
There are a few terms that yo
u will need to know so that you can understand what the different
parts of the seam are:
the line on which the garment is cut out
STITCHING LINE/SEAM LINE:
the line on which the seam is sewn
the area of fabric between the stit
ching line and the cutting line. This is
usually 5/8" or 1.5cm. Some patterns allow more in some areas, and some allow less.
