Why the JLS deli sandwich line
Building deli sandwiches by hand is a labor problem waiting to scale you out.
Manual sandwich assembly is repetitive, labor-intensive work that is hard to staff and hard to keep consistent at volume — and direct hand contact with sliced meats and cheese raises food-safety concerns. At higher output, every layer depends on an operator, and the consistency and throughput both suffer.
Components in. Consistent sandwich out. The JLS integrated line is configured around your recipe, components, and facility — so one of the most repetitive jobs in prepared foods becomes one of the most predictable.
Applications & package types
The sandwich line — pick, stack, pack
JLS builds the complete deli sandwich assembly line and takes full system responsibility. Automatic slicing and vision-guided IP69K-capable delta robots place sliced deli meats, cheese, and toppings in sequence, building a consistent sandwich every cycle. JLS integrates the full line: automatic slicing, coordinated component in-feeds, vision-guided robotic assembly, thermoform or flow-wrap packaging, inline inspection, and robotic case packing — FAT-tested in York, PA.

The engineering behind the line
Every part of the sandwich line was designed, built, and programmed under one roof — from custom end-of-arm tooling to IP69K-capable vision-guided delta robots to component in-feeds, flow wrapping, inspection, case packing, and a single control platform. Backed by multiple patents and a proven track record assembling food products at production speed.
Designed to get wet — IP69K-capable washdown
Open-frame design, sloped surfaces, and NEMA 4X controls rated to IP69K-capable levels for the high-pressure, high-temperature washdown of a hot prepared-foods environment. The delta robots and tooling are built for the food zone from day one.1
Vision-guided delta robotics
Vision identifies the exact position and orientation of each component as it arrives, so IP69K-capable delta robots pick and stack it precisely — bread, sliced meats, cheese, then toppings — with no fixed guides. Repeatable, vision-controlled placement builds a consistent sandwich every cycle.
Custom end-of-arm tooling
Each component — bread or rolls, floppy sliced meats, cheese, toppings — needs a different touch. JLS designs and lab-tests custom end-of-arm tooling for every component so robots handle even tacky, draping slices gently and reliably at speed. Tooling is food-safe and built for washdown, configured to your exact recipe.
On-the-fly changeover
Switch sandwich recipes and formats from the HMI. Recipes drive the robots, component in-feeds, and packaging so different SKUs run with minimal mechanical adjustment — keeping a fast-moving prepared-foods line productive across its product mix.
Full-system integration
JLS integrates the whole line — coordinated component in-feeds, vision-guided robotic assembly, flow wrapping, inline checkweighing, x-ray and metal detection, and robotic case packing — as one system with single-source accountability. The complete line is proven with a full-system factory acceptance test (FAT) before it ships.
Single control platform & in-house software
One B&R platform runs the component in-feeds, robots, wrapping, and inspection from a single HMI — no patchwork of separate control systems. Software is written and owned entirely by JLS, so new recipes and remote support come directly from the team that built your line.
Options & add-ons
More ways to fit your line.
Multi-component builds & formats
The robots build the full stack — bread, sliced meats, cheese, and toppings — in the sequence and count your recipe calls for, from a simple two-layer build to a fully loaded sandwich. Vision keeps every layer aligned, sandwich after sandwich.
Components and sequence are part of the recipe — switching is an HMI change, with no mechanical re-tooling.

How the JLS sandwich line assembles, wraps, and packs
Five integrated steps. Components in, wrapped and inspected sandwich out — built layer by layer.

Line configuration
Deli sandwich assembly line — what goes into it
Every deli sandwich line is configured to the product, the facility, and the target rate. The table below shows the typical components JLS and integration partners (Reiser) bring together. Contact JLS to scope yours.
| Line station | Typical equipment / capability |
|---|---|
| Slicing & in-feed | Automatic slicing of meat, cheese, and toppings; gravity or conveyor in-feed to assembly zone |
| Component singulation | Centrifugal feeders or indexing belts to present components in orientation for pick |
| Vision-guided stacking | IP69K-capable delta robots with 2D/3D vision locate and place each layer — meat, cheese, condiment, topping — onto bread or roll |
| Robot type | 4-axis delta robots, IP69K-capable (washdown-rated); typically 6–8 robots per line |
| End-of-arm tooling | Custom EOAT per product; vacuum or mechanical; tool-less swap for changeover |
| Primary packaging | Flow wrap (horizontal or vertical) or thermoform; integrated inline with robotic assembly |
| Inspection | Checkweigher, metal detection, or vision inspection — inline before case packing |
| Case packing | Automated case erecting (upstream), loading, and sealing — Hawk 2-axis robot arm or delta-based case packer |
| Controls | B&R Automation; single HMI across all stations; recipe-driven changeover |
| Sanitation level | IP69K-capable delta robots; construction level configured per facility (cleanable or full washdown) |
| FAT & commissioning | Full-line FAT in York, PA with customer product before shipment |
| Integration partner | JLS Automation + Reiser (primary partner); line-specific scope confirmed at assessment |
* The line’s IP69K delta robots are washdown-rated; sanitation levels are configured per application. Contact your JLS representative for full details on your line.
