Occupational Safety Training for Mattress Edge Sewing Machine Operation

1. Overview of Mattress Edge Sewing Machines

a. What is a mattress edge sewing machine?

A mattress edge sewing machine is a specialized device in the mattress manufacturing and processing industry. This machine is designed to perform tasks such as sewing the edges around mattresses, creating strong and even stitches that help the mattress have a finished and durable appearance.

Key features of a mattress edge sewing machine:

• Main function: The machine sews edges or seams around the mattress. This not only enhances the mattress’s aesthetics but also protects the mattress edges from damage or tearing.
• Design: The machine typically has a robust structure with specialized parts to handle thick fabrics and materials. Some machines are equipped with automatic mechanisms to adjust stitch length and depth to suit mattress size and thickness.
• Applications: Besides sewing mattress edges, the machine can also be used to sew other large and thick products like chair cushions, sleeping bags, and other textile products.
• Technical specifications: Mattress edge sewing machines often feature high sewing speeds, continuous operation capability, and powerful transmission parts to handle tough and thick materials.
• Technology: Some modern mattress edge sewing machines come with automatic features such as speed adjustment, thread type switching, and even thread tension control to ensure sewing quality.

b. Operating principle of mattress edge sewing machines

Material preparation and machine setup

• Prepare the mattress: First, the mattress needs to be aligned so that the edges or fabric layers are ready for sewing. The mattress is usually placed on the machine’s working table.
• Set up the machine: Adjust machine settings including thread type, sewing speed, and seam size. Some machines feature automatic adjustment functions for these parameters.

Drive mechanism

• Drive components: The machine uses a drive mechanism to feed the thread and fabric through sewing parts. The drive includes motors and wheels that pull the fabric under the needle.
• Motor: The motor powers the needle and other machine parts. It can be an electric motor or pneumatic motor depending on the machine design.

Sewing process

• Needle and thread: The machine has one or more needles that work with the thread to create stitches. The needle penetrates the fabric while the thread is pulled through to form stitches.
• Feed and tension system: This system ensures the fabric is held firmly and thread tension prevents breaking or wrinkling, ensuring consistent and strong stitches.
• Edges and cushions: The machine may have specialized parts to create secure edges around the mattress, including guides and cushions to hold the fabric in place and sew precise seams.

Finishing steps

• Trim excess thread: After sewing is complete, the machine may have a function to cut off excess thread to ensure a neat finished product.
• Quality inspection: Seams and edges are checked to meet quality standards. Adjustments or repairs may be made if necessary.

Benefits of automatic features

• Automatic adjustments: Some modern machines can automatically adjust parameters like sewing speed, thread tension, and stitch length to improve accuracy and efficiency.
• Automatic lift mechanism: The machine may have an automatic lift feature to easily handle large or thick mattresses.

Safety and maintenance

• Safety system: Machines usually have safety features like needle locks, motor protection, and sensors to prevent accidents and damage.
• Regular maintenance: To ensure efficient operation, regular maintenance like lubricating moving parts and checking consumables is required.

c. Industries using mattress edge sewing machines

d. Occupational safety card

After completing the occupational safety training course and passing the exam, workers will be issued an occupational safety card (commonly known as occupational safety certificate for group 3).

The group 3 safety card clearly shows information such as full name, date of birth, job, and specific work environment. It also includes training duration, official red stamp, and signature confirming course completion.

According to regulations detailed in Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have a labor contract, the employer must sign, stamp, and certify the occupational safety card for the group 3 worker after the training and exam from the occupational safety training unit.
• If the worker is freelance or temporary and does not have a labor contract, the training unit must sign, stamp, and certify the occupational safety card after the training and exam.
