Manual cutting equipment in 8

textile cutting operations

8.1 Introduction

The manual cutting process is performed by a variety of cutting machines of differing
designs. They may be divided in two groups according to whether their operation
is movable or static. The cutting process may be performed by straight, round, or
band knives. These machines are designed to cut fabrics with differing properties.

8.2 The straight-knife cutting machine
Straight-knife cutting machines are used to cut components of differing size. They are
moved along the cut contours, while the fabric spread remains in a fixed position (see
Chapter 7, Sections 7.2.1 and 7.2.2). The machines are manoeuvrable and capable of
curvilinear cutting. Depending on their size and power, these machines can cut spreads
of different heights and fabrics of different thickness (see Fig. 8.1).
The maximum height of a cut spread is 300 mm. The weight of the machines varies
between 5 and 20 kg. Heavier machines are less manoeuvrable. Small-capacity pro-
duction units may use only straight-knife machines.
A straight-knife machine has the following main parts: (1) upper handle, (2) elec-
trical cable, (3) motor, (4) side handle, (5) knife sharpener, (6) stand, (7) presser foot,
(8) straight knife, and (9) base plate with rollers (see Fig. 8.2).
