Cutting is one of the processes in the garment manufacturing. In bulk garment manufacturing, multiple fabric layers are cut at a time by means of cutting machines. Different types of cutting machines and equipment are available for cutting fabrics and machines are used as per requirement and production volume. Semi-automatic and automatic improves cutting room productivity and improves cutting accuracy.
Different Types of cutting Machines
Cutting machine and equipment can be categorized as following
Semi-automatic cutting machine
Fully automatic cutting machine
1. Manual cutting
Hand scissors are used for cutting fabric plies manually. Hand scissors are not machines but very useful cutting equipment. Factories may have semi-automatic and fully automatic machines for fabric cutting, but can’t avoid use of hand scissors in cutting section. Scissors are common tool in cutting process and hand scissors ha many use in cutting room.
2. Semi-automatic cutting machines
Straight Knife cutting machine:The straight knife is a common means of cutting lays in conventional cutting rooms because it is versatile, portable, cheaper than a band knife, more accurate on curves than a round knife and relatively reliable and easy to maintain. Even if a band knife is used for the main cutting operation, a straight knife would be used to separate the lay into sections for easier handling.
Band Knife cutting machine:
Band knives are used when a higher standard of cutting accuracy is required than can be obtained with a straight knife. Pieces to be cut are first cut on a block, and then cut exactly on a band knife.
Round knife cutting machine:
A round knife is used only for straight lines or lower no of lays of relatively few plies.
Die cutting machine:
This machine is useful where small motifs with particular shape and pattern and accuracy in cutting are needed.
3. Automatic cutting machines
There are different types of automatic fabric cutting machines. Here majorly used cutting machines in the garment industry are shown.
Computerized cutting machine:
Computerized cutting machines are used where high volume of garments is manufactured. This machine cuts fabric layers as per command given in computer system. Automatic cutting machine is also known as CNC machine. In the automatic cutting room, fabrics are spread on the table by auto spreader and the lay is positioned in the cutting table prior to automatic cutting. Many videos are available on the Youtube for automatic cutting machines.
Rib cutting machine:
Narrow fabric tape of rib is cut from knits fabric. Ribs are used in t-shirts neck finishing or piping operations and many other knits apparel manufacturing
Laser cutting machine:
Instead on blade fabric layer is cut by laser rays. Laser cutting machine is also computer controlled machine.
