Technical guides on industrial machinery
Everything we publish comes from real workshop questions. None of these guides is a catalogue page: they are the answers we give on the phone when someone calls us before buying, or when a machine they already have doesn’t do what they expected. The guides are written in Spanish.
- 30 technical guides
- 4 videos and real cases
- Sewing, welding and setting up a workshop

Before buying: how to choose a machine
- How to choose the right industrial sewing machine for your business: the right order of questions: material, piece, volume, and only at the end the model.
- Compound, double or bottom feed: which do you need, the feed system decides which materials you can sew. It is the first decision, not a technical detail.
- Industrial stitches explained: 301, 401, 504, 514, 516 and 607, what those numbers on data sheets mean and which one matches your product.
- Frequently asked questions when choosing a machine: the most common doubts, answered briefly.
- M-Type and Delta Precision range: what sets Dürkopp Adler’s heavy-duty series apart.
Leather and upholstery
- Which machine you need to sew leather: feed, piece geometry and flatbed, cylinder bed or post bed. With catalogue models and their prices.
- Sewing machines for upholstery: an upholsterer doesn’t sew one material, they sew four. How to choose without falling short.
Welding and heat sealing technical textiles
- What heat sealing is and when you need it: what heat sealing really means: the tape, the hot air and why every stitch in a waterproof garment is a hole.
- Heat sealing is not welding: almost everyone calls four different processes heat sealing. What each one really does.
- Ultrasonic, hot air or hot wedge: the material decides: why thick PVC isn’t welded ultrasonically.
- Which materials can be ultrasonically welded (and which can’t): cotton doesn’t melt; thermoplastic coatings do.
- How an ultrasonic welding machine works: sonotrode, anvil wheel and why the machine doesn’t need to heat up.
- Sew or weld: when it pays to change process, sewing pierces; welding doesn’t. When that changes the product.
- What are the parts of a heat sealing machine called? Nozzle, heater, rollers and tape guide, with a photo of a PFAFF 8303.
- Why doesn’t the heat sealing tape stick? Step-by-step guide in three levels: tape, fabric, temperature, air, speed and pressure.
Setting up and maintaining the workshop
- Which machines you need to set up a garment workshop: where to start when the budget doesn’t stretch to everything.
- How to set up a cutting room: from the hand knife to CNC, the point at which automatic cutting pays for itself.
- Preventive maintenance: the schedule that avoids the costly breakdown, an industrial machine gives warning before it breaks.
- Industrial needle guide: system, size and point, the cheapest part of the machine and the one that causes the most problems.
