Spring for higher load and diameter of laid-on sliver are fitted with pantograph. A triangular bottom is required for the free movement of the pantograph, so that the spring collapses uniformly. The bottom of the pantograph is especially designed to accommodate the collapsed convolutes which ensure uniform movement of sliver, not allowing any tilting of the top plate.
Spring are the heart of spinning cans. it is made of high carbon spring steel wire. they are heat treated to ensure fatigue-free performance, uniform collapsibility and release, these are the quality spring of VCANS for fitment in modern spinning machines. Plastic bottom covers are so designed that they allow clustering of coils of the spring within themselves. this allow additional capacity for the sliver to fill in.
Box type spring assembled with plastic bottom cover and steel triangles and also plastic top cover specially designed with right thickness, to ensure no deformation.
Top Ring and Top Band made of stainless steel / galvanized steel.
Top Ring and Top Band holds the cylinder firmly and prevent it from loosing shape.
