How to Inspect a Pneumatic Double Jersey High-Foot Knitting Machine

This is an inspection guide rather than a second general overview of the same machine family. With the old playback source removed, the page now explains how to examine a pneumatic double-jersey high-foot machine before shipment and what evidence should be attached to the inspection record.

Begin with identity and completeness

Match the nameplate, purchase order and configuration sheet before running. Count or verify feeders, identify diameter and gauge, check the cylinder/dial arrangement, take-down form, controls, voltage and supplied accessories. Photograph serial identification and record any item that is packed separately so it cannot disappear between inspection and installation.

Inspect the machine in controlled stages

With guards and utilities checked, observe lubrication and manual or low-speed rotation before increasing speed. Test stop motions, emergency devices and the specified pneumatic actions. During the fabric run, note yarn lots, recipe, speed steps, stops and the length held at stable conditions. Inspect both fabric faces under consistent light rather than judging the machine from movement alone.

Close every observation with evidence

Classify each issue as accepted, corrected and retested, open before shipment, or site-dependent. Attach photographs, fabric labels and the agreed result to the record. A spoken promise or a short clip cannot show whether a fault was resolved; the close-out entry should name the corrective action, verifier and date.

Evidence checklist for this topic

Decision point	Evidence to retain
Document check	PO, technical sheet, nameplate and packing scope agree
Static check	Guards, lubrication, wiring, air preparation and fasteners
Functional check	Stops, controls, pneumatics, take-down and speed stages
Fabric check	Yarn, settings, stable length, both faces and defect map

Boundary: Inspection evidence should belong to the actual ordered unit; a clean demonstration machine nearby is not a substitute.
