RK PSC 320 PVC Shrink Sleeve Cutting Machine – Print Mark Registered Sleeve Cutter up to 320 mm

A PVC shrink sleeve cutting machine is a registered cross-cutter for flattened sleeve tubing. It feeds the web forward by the sleeve length, checks the position against the printed register mark, and cuts. Two things give it accuracy. The servo feed advances exactly the same distance each stroke, and the print mark scanner compares that advance with the actual mark on the film and trims the next feed to remove any drift. Over a long run the cut line therefore stays exactly where the artwork puts it.

The PSC 320 is built for film widths up to 320 mm, which covers the usual lay-flat widths of bottle sleeves, jar sleeves and cap bands. The cutting unit uses a mechanical eccentric movement for a clean, repeatable stroke, and a conveyor with a 0.5 HP geared motor and variable frequency drive carries the sleeves away and stacks them.

Servo Feed With Panasonic Print Mark Scanner

An electronic servo motor feeds the web a fixed length every stroke, and a Panasonic print mark scanner reads the register mark and corrects the pull before each cut. Length accuracy holds from the first sleeve to the last.

15,000 to 18,000 Strokes an Hour

Cutting speed is 15,000 to 18,000 strokes per hour depending on sleeve size, with each stroke producing one finished sleeve.

320 mm Maximum Film Width

The machine accepts seamed sleeve webs up to 320 mm wide, matching the output of the RK PSG 650 glueing machine slit to sleeve width.

Cantilever Unwind to Ø 700 mm

The unwind takes rolls to Ø 700 mm on a cantilever mounted 3 inch multi-bladder air shaft, so one operator loads the roll from the side without a second person or a lifting aid.

Ultrasonic Edge Guide and Mechanical Brake

An imported electronic ultrasonic edge scanner guides the web into the feed, and a mechanical brake system on the unwind holds tension so the mark scanner sees a steady web.

Mechanical Eccentric Cutting Unit

The blade is driven by a mechanical eccentric movement, giving a firm, square cut through the two layers of the flattened tube at every stroke.

Motorised Collection Conveyor

Cut sleeves land on a conveyor driven by a 0.5 HP AC geared motor with a variable frequency drive, and stack neatly at the end for counting and packing.

Static Elimination

PVC film picks up static charge, and charged sleeves cling to each other instead of stacking. A static eliminator on the web path removes the charge before the cut.

The seamed sleeve roll from the glueing machine is loaded on the cantilever air shaft of the unwind. The ultrasonic edge scanner lines the web up and the mechanical brake sets the tension. The operator enters the sleeve length, and the servo feed draws the web forward by that length for each cycle.

As the web advances, the Panasonic print mark scanner reads the register mark printed on the film. If the mark arrives early or late, the scanner corrects the feed so the blade comes down exactly on the cut line. The eccentric cutting unit makes the stroke, the finished sleeve drops onto the conveyor, and the next feed begins. At 15,000 to 18,000 strokes an hour the sleeves arrive at the end of the conveyor in a continuous stack, discharged and ready to box or send to a sleeve applicator.

• Shrink sleeves for bottles – full-body and partial sleeves for water, beverage, juice and dairy bottles.
• Cap seals and neck bands – short PVC shrink sleeves for bottle caps and tamper evidence.
• Shrink sleeve labels for food and FMCG – jars, tubs and cans in shrink sleeve packaging.
• Cosmetics and personal care – sleeves for shaped containers.
• Pharma – tamper bands on syrup and supplement bottles.
• Shrink sleeve manufacturers – cutting seamed tubing into finished sleeves for customers.

The RK PSC 320 is specified for seamed PVC shrink sleeve tubing up to 320 mm lay-flat width on rolls to Ø 700 mm with a 3 inch core. The print mark scanner needs a printed register mark on the film. Other shrink sleeve films can be discussed with RK, since blade, feed and static settings are matched to the film. Send RK your film type, thickness, lay-flat widths and sleeve lengths so the machine is set up for them.

RK Label Printing Machinery Pvt. Ltd. has manufactured label printing and converting machinery in Ahmedabad, Gujarat since 1995, runs three manufacturing units and supplies customers in 23+ countries. The PSC 320 and PSG 650 are designed as a pair, so the roll that comes off the glueing machine loads straight onto the cutter, and RK's flexo presses and slitters cover the printing and slitting steps before them. One supplier configures the whole shrink sleeve line to the customer's film and sleeve sizes.

• Lay-flat width: the PSC 320 cuts up to 320 mm. Measure your widest flattened sleeve.
• Sleeve length and output: at 15,000 to 18,000 strokes an hour, calculate sleeves per shift against your orders.
• Roll size: Ø 700 mm unwind on a 3 inch shaft; match it to the roll your glueing machine produces.
• Register mark: confirm your artwork carries a print mark for the scanner.
• Collection: the conveyor stacks sleeves; tell RK if you feed an applicator directly.
• Glueing upstream: pair with the RK PSG 650 for seaming.

The price of the RK PSC 320 depends on the feed and cutting configuration, the conveyor and any options you require. Prices are quoted ex-works Ahmedabad with GST at 18% applicable. Transport and stay for the RK engineer who installs the machine and trains your operators at your site are borne by the customer. Share your sleeve widths, lengths, roll sizes and output target with RK and the team will recommend a configuration and quote against it.
