Fully automatic cutting, splicing and winding

CM Fabric cutting and splicing machine

The textile cord cutting and splicing machine from CM guarantees fully automatic operation to unwind coated textile cord from bales which is then cross-cut at 90°, overlapped, spliced and wound up to cassettes.

Functional description

A compensating loop controls the fabric let-off station as a function of the shearing capacity.
Draw-off rolls with length measurement operate in conjunction with a special belt conveyor to determine the width of the strips that are to be cut. After the cut, performed by special self-setting shears, the strips are transported by a vacuum system and belt conveyor to the splicer which overlaps and joins the ends. The strips are wound up to cassettes via a compensating loop.

More than 20 cuts per minute

Machine components

Let-off facility

The let-off station with let off rolls and festoon loop can be used to unwind both cassettes and bale-loaded carriages. Rewinding and splicing facilities are available as options.

Cutting machine

Precise fabric advance is guaranteed by a cutting machine table consisting of a pair of feed rollers and a belt conveyor. The fabric plies are cut by guillotine shears especially developed for this machine and operating by a drawn swing cut in conjunction with a self-adjusting lower blade.

Transfer mechanism and belt conveyor

A vacuum system transports the cut strips from the cutting machine table to a transverse belt conveyor, depositing them centrally onto the belt. The vacuum system with linear axle is driven by a three-phase servomotor. An existing mains or separate vacuum pump can be used for vacuum generation.

Splicer and draw-off roll

A combination of mechanical stops and non-contact scanners position the beginning and end of the strips to give the desired 3 mm overlap.
The actual splicing operation is performed by a pneumatically actuated bar. The draw-off roll transports the material after a splice check is performed.

Wind up station

The strips are controlled by a compensating loop while they are wound onto two cassettes mounted in tandem thus ensuring continuous operation.

Control

The design of the electrical control conforms with current EN guidelines. Machine operation is controlled by a freely programmable control system from Beckhoff.
All operating controls, together with a monitor, are conveniently arranged on a central control console.
This enables editing of a maximum of 100 recipes, machine data and parameters, and the display of operating and error messages to assist diagnosis. The machines safety system consists of special hardware-based safety circuits.

The following operating modes are possible:

• Automatic mode
• Manual mode
• Set-up and maintenance mode

Options

• Doubling station for shoulder strips
• Width measurement
• Prickle facility
• Double wind-up station

Layout

The machine can be supplied as either a right- or left-handed version as required by the customer's specific production conditions.
Modifications can be made to the let-off and windup station.
