Uses: Bartacking sewing machines are used
frequently in apparel manufacturing processes for reinforcing areas of garments
that are subject to stress and strain. Some of the most common applications of
bartacking include:
- Pocket corners: Bartacks are often used to reinforce
the corners of pockets on pants, jackets, and shirts, which are subject to
frequent wear and tear.
- Belt loops: Belt loops on pants and skirts are
also commonly reinforced with bartacks to ensure they can withstand the stress
of a belt being threaded through them.
- Zippers: Bartacks can be used to reinforce the
top and bottom of a zipper, as well as the ends of the tape where the zipper is
sewn into the garment.
- Seams: In some cases, bartacks may be used to
reinforce seams that are subject to stress or to prevent them from coming apart
during use.
- Straps: Bartacks are often used to reinforce
straps on backpacks, messenger bags, and other types of bags that are designed
to carry heavy loads.
Overall, bartacking is an important technique in
apparel manufacturing that helps to ensure the durability and longevity of
garments. Bartacking machines are designed to make this process efficient and
precise, allowing manufacturers to produce high-quality garments that can
withstand the demands of everyday wear and use.
Components: A bartacking sewing
machine typically includes the following components:
- Needle and needle bar: The needle and
needle bar are responsible for puncturing the fabric and creating the stitch.
The needle bar moves up and down to drive the needle through the fabric, while
the needle itself varies in size and shape depending on the specific bartack
being created.
- Bobbin: The bobbin holds the lower thread and
is positioned below the needle plate. As the needle punctures the fabric, it
pulls up the lower thread to create the stitch.
- Feed dogs: The feed dogs are a set of teeth-like
mechanisms that move the fabric through the machine as it is sewn. In a
bartacking machine, the feed dogs can be adjusted to move the fabric at
different speeds or in different directions, which is useful when sewing around
corners or curves.
- Tension discs: The tension discs hold the upper
thread and help to regulate the amount of tension on the thread as it is sewn.
This is critical for creating a strong, consistent stitch.
- Presser foot: The presser foot holds the fabric in
place as it is sewn, ensuring that it stays flat and does not shift or bunch up
during stitching.
- Control panel: The control panel on a bartacking
machine allows the user to adjust the machine settings, such as stitch length,
width, and tension, as well as needle position and other features.
- Thread cutter: A thread cutter is typically located
on the side of the machine and is used to trim the thread at the end of a seam
or bartack.
Overall, a bartacking sewing machine is similar in
many ways to a standard sewing machine, but includes specialized features and
components that are designed to create strong, durable bartacks in specific
areas of garments.
Problems and Solutions: Bartacking sewing
machines, like any other type of machine, can experience mechanical problems
that can affect their performance and productivity. Here are some common
mechanical problems that can occur with bartacking machines and some solutions
to address them:
- Needle breakage: This can occur if
the needle is bent or the wrong size, or if the machine is sewing through thick
fabric or multiple layers. Solution: Make sure you are using the correct needle
for the fabric, adjust the needle position, and check that the thread tension
is set correctly. You may also need to slow down the machine speed or use a
more appropriate needle for the thickness of the fabric.
- Thread tension problems: If the upper or
lower thread tension is incorrect, it can result in poor stitch quality, thread
breakage, or other issues. Solution: Check the thread path to make sure it is
correctly threaded and that the tension discs are clean and functioning
properly. Adjust the tension as needed, and make sure the bobbin is correctly
inserted and wound.
- Skipped stitches: This can occur if
the needle is dull or bent, or if the fabric is not being fed through the
machine evenly. Solution: Check the needle and replace if necessary, make sure
the fabric is being fed smoothly and evenly, and adjust the stitch length or
tension if needed.
- Machine jams or stops: If the machine jams
or stops unexpectedly, it could be due to a variety of issues, including a
clogged bobbin case, tangled thread, or other mechanical problems. Solution:
Turn off the machine and inspect it carefully, removing any debris or thread
that may be causing the jam. If the issue persists, consult the manufacturer's
instructions or a professional technician for assistance.
- Inconsistent stitching: If the stitching is
uneven, it could be due to issues with the needle, tension, or fabric feed.
Solution: Check the needle and adjust the tension, and make sure the fabric is
being fed through the machine evenly. You may also need to slow down the
machine speed or adjust the stitch length.
Overall, regular maintenance and careful attention
to detail can help prevent many common mechanical problems with bartacking
sewing machines. If you encounter persistent issues, it is always best to
consult the manufacturer's instructions or a professional technician for
assistance.
Conversion a Bartack Machine into Button Stitch: In some cases, a bartacking machine can be converted into a button stitch
machine by swapping out certain parts. The specific parts that need to be
changed can vary depending on the make and model of the machine, but some
common parts that may need to be replaced include:
- Needle plate: The needle plate on a button stitch
machine may have a different configuration or size than the plate on a
bartacking machine, so it may need to be swapped out.
- Button clamp: A button clamp is a specialized
component that holds the button in place while it is being sewn onto the
fabric. A button stitch machine will typically include a button clamp, while a
bartacking machine may not.
- Button guide: A button guide is a mechanism that
helps to position the button correctly for sewing. A bartacking machine may not
include a button guide, so one may need to be added or replaced in order to
convert the machine for button stitching.
- Thread cutter: A button stitch machine may have a
different type of thread cutter than a bartacking machine, so this component
may need to be replaced as well.
- Feed dogs: The feed dogs on a button stitch
machine may be configured differently than those on a bartacking machine, so
they may need to be swapped out or adjusted.
Overall, converting a bartacking machine to a button stitch machine can be a complex process that requires a thorough understanding of the machine's components and functions. It is recommended that this type of conversion be performed by a professional technician with experience in sewing machine repair and maintenance.
- Bartack machine is used to stitch where deep lockstitch sewing is needed. Jeans pant belt loop joining, fishing net, cap hole, etc are stitched by bartack sewing machine.
