Marjan Polymer Industries supplies and configures Sample Warping Machines in Pakistan for economical preparation of short warps used in fabric development, weaving trials, teaching and limited sampling. Often called a mini warper or warp-sampling machine, the equipment lays yarn on a controlled drum in the required end sequence before transferring the prepared warp to a sample beam.
The machine is selected around sample width, warp length, total ends, colour repeat, yarn type, tension range, package count, drum geometry, beam dimensions and the downstream sample loom. MPI can provide a compact single-end system or evaluate more automated multi-guide and colour-change solutions when the sampling programme requires higher productivity.
Efficient Warp Preparation for Sampling
Conventional warping can consume substantial yarn and setup time when only a few metres of fabric are needed. A sample warper builds the required warp from fewer yarn packages and allows colour order, end count and repeat to be changed between developments.
Accuracy remains essential. Uneven end spacing, incorrect colour order, tension variation or poor beam transfer can appear as streaks, width changes and warp stops during weaving. The warper, creel, traverse, lease and beaming method must work as one system.

Warp Plan, End Count and Colour Sequence
The warp plan defines total ends, selvedge ends, colour order, repeat and yarn assignment. For a single-end machine, the guide lays the required number of ends for one yarn before the operator changes packages according to the sequence. Automated systems can manage multiple guides or yarn changes.
Input should be checked against the sample-loom reed plan before warping. A digital recipe can reduce counting errors, but yarn labels, package identity and visual confirmation remain important for complex colourways.
Drum Geometry and Yarn Laying
The drum provides the controlled path on which the warp is built. Circumference, usable width, surface finish and dynamic balance determine the available sample lengths and safe speed. The traverse lays successive ends at the programmed spacing without overlap or excessive gaps.
Guide alignment and servo calibration should be verified across the full width. The practical laying accuracy is influenced by yarn diameter, tension, vibration and surface friction, not only by the controller’s command resolution.
Yarn-Tension Control
Constant tension helps produce equal end length and a stable sheet. Package unwinding changes as the package empties, while knots, ballooning, friction and elastic recovery can disturb tension. The creel path should therefore use suitable guides and tensioners.
Fragile filaments, elastomeric yarns, glass, carbon and aramid may require driven feeders, low-friction ceramics, antistatic control or reduced speed. Tension limits are established by trial and recorded with the warp recipe.
Length Measurement and Automatic Stop
An encoder or calibrated measuring system tracks drum revolutions and calculated yarn length. The machine can decelerate and stop at the programmed count, improving repeatability between colour groups and repeat orders.
Measured length should be verified periodically against a reference, especially after drive, encoder or drum changes. Allowance is required for leasing, tie-in, beam transfer and sample-loom waste.
Leasing and Yarn-Order Control
Lease crossings preserve end order and make drawing-in or beam transfer manageable. Manual systems use rods or strings inserted at defined positions, while automated machines can form leasing and sizing separations during the programme.
Missing or incorrect leases can make an otherwise accurate warp difficult to use. The lease plan should identify colour changes, repeat boundaries and any sections required by the downstream loom.
Beam Transfer and Sample-Loom Compatibility
After warping, the sheet is transferred from the drum to a sample beam under controlled tension. Beam barrel diameter, flange diameter, working width, shaft ends and mounting must match the loom or the transfer fixture.
The transfer path should prevent crossed ends, edge collapse and differential stretch. A pressure roller, expansion comb or guided winding device may be included according to warp width and yarn type.
Yarn Compatibility
- Cotton and cotton-blend spun yarns
- Polyester, nylon and other synthetic filament or spun yarns
- Wool blends and specialty apparel yarns where tension is suitable
- Glass, carbon, aramid, jute and technical yarns after contact-material and safety review
- Elastic yarns with positive or driven feeding where required
- Novelty and effect yarns subject to guide, package and tension trials
A stated tex range does not prove every yarn will run at maximum speed. Package quality, hairiness, twist, friction, stiffness and elasticity all affect performance.
Controller and Recipe Functions
A computerized system can store sample width, length, end count, traverse pitch, colour groups, speed and stop points. An HMI can display progress, alarms, current yarn group and maintenance reminders.
Options can include barcode or job identification, recipe backup, network transfer and production records. The exact software, licensing and file interface must be defined before supply.
Integration with CAD and Sample Weaving
Textile CAD can create a fabric design, colour order, warp plan and draft. The warping data must then be translated into a machine-compatible recipe and checked against sample-loom capacity.
MPI can define a connected sampling workflow covering sample warping, single-end or beam sizing, drawing-in and dobby/Jacquard sample weaving. Each interface and data handoff is listed in the project scope.
Productivity and Changeover
Sample-warper productivity depends on total ends, warp length, colours, package changes, leasing and beam transfer. A high drum speed has limited value if the job requires frequent manual changes or long setup.
Useful performance measures include complete warp preparation time, yarn waste, recipe accuracy, stops, transfer time and successful first weaving. Standard operating procedures and labelled yarn staging can significantly reduce errors.
Quality Checks and Acceptance Criteria
| Check | Purpose | Acceptance Method |
|---|---|---|
| Width and end spacing | Prevents crowding, gaps and edge variation | Measured at defined drum positions |
| Length repeatability | Supports equal ends and repeat jobs | Encoder verification and sample measurement |
| Colour sequence | Confirms design accuracy | Recipe-to-warp visual count |
| End tension | Controls stretch and beam quality | Calibrated tension test on representative yarn |
| Automatic stop | Prevents overrun and yarn damage | Programmed length and yarn-break trials |
| Beam transfer | Confirms downstream usability | Transfer and sample-loom mounting trial |
Utilities and Installation Requirements

Safety and Operator Protection
The rotating drum, traversing guide, drive and beam-transfer mechanisms create entanglement and pinch hazards. Required safeguards include emergency stop, fixed or interlocked guards, an accident-protection bar and controlled deceleration.
Loose clothing, hair and tools must be kept away from moving yarn and drums. Technical fibres may require dust extraction, cut-resistant handling or respiratory controls based on the yarn supplier’s safety information.
Cleaning and Preventive Maintenance
Remove lint, broken ends and yarn finish from guides, tensioners, drum and sensors. Precision guides should be inspected for grooves that can damage filament. Keep the drum surface clean and free from adhesive residue.
Scheduled work covers drive belts or couplings, bearings, brake, servo traverse, encoder, guide alignment, emergency devices and electrical connections. Recipe backups and calibration records should be maintained.
