Manual Leather Edge Coating Machines:
In the early days of leather processing, leather craftsmen relied on their skills and hands to polish edges. A manual machine puts the control completely in one's hands while adding a personal touch to each item. While humans can make mistakes, manual machines give accessories a unique and original look. However, unassisted machines are slow because only one piece can be worked on at a time. Manoeuvring the tool around edges is challenging, especially complex curves and small details where precision is important. Fragile materials may get damaged or worn out quickly from constant manual use.
Crank Leather Edge Coating Machines:
Although still requiring some manual effort compared to fully automated options, crank/hand-lever machines offer a better experience and greater capacity. By incorporating a hand crank or lever, they provide simple exercise and assistance without requiring electricity, enabling the coating of edges more comfortably and reliably. The process becomes less demanding physically and more efficient, as the machine can be used to coat multiple items sequentially while featuring an edge guide that helps align pieces consistently every time.
Edge Trimming and Rounding Machines:
Portable leather edge rounders and trimmers allow busy leather craftsmen to visit a bench, worktable, or even an outdoor location whenever inspiration strikes. Their ability to be easily transported and used at any location eliminates the need to bring items to this device for further processing, greatly enhancing versatility and convenience. With simple equipment and affordable maintenance costs, these machines are perfect for those who desire freedom in their creative process without being constrained by fixed installations.
Pneumatic Leather Edge Coating Machines:
Specialized tools offer increased personalization, faster turnaround, and record production capacity by coating leather edges using solely the power of air pressure without any direct or physical contact between machine and leather, making it fundamentally distinct from other methods of polishing leather edges. Because no external force or intervention is involved, one can coat an unprecedented number of pieces of leather material in a much shorter period compared to any previously utilized technique, thus enabling unrivaled levels of efficiency and output. This represents a groundbreaking advancement unprecedentedly in manufacturing capabilities, which now sets new standards previously thought impossible.
Leather edge painting machine specifications depend on the machine type and include various features. The critical specifications include the strength and size of the machine, coating method, feedstock applicability, coating width, sealing technology, drying time, temperature range, power requirements, and additional features.
Edge coating machines' strength, sizes, and coating methods:
Strength and size:
An edge leather coating machine can have a mass of one to three hundred kilograms and dimensions of about 400 mm x 400 mm x 700 mm. Bench-top/floor-standing machines are preferred for DIY use and small-scale production. Their sizes are more convenient for workshops and domestic use. Industrial-scale machines are preferred for more extensive operations and have bigger sizes.
Coating method:
A roller-based edge leather coating machine often has a two-roller or four-roller setup. The two-roller setup comprises a feeding roller and a receiving roller. In the four-roller setup, the priming roller and the finishing roller perform the coating part. The spray machine can have a pneumatic or electric spray gun.
Applicability, coating width, sealing technology, and drying time:
Applicability:
Some machines can apply the coating on various materials, such as leather, textile, and PVC. Others are limited to leather (natural and synthetic) and rubber.
Coating width:
Generally, a machine will be able to coat a width of about 160 mm, which is sufficient to cover a leather edge of any size.
Sealing technology:
Direct coating machines and indirect coating machines (the latter apply the coating to a substrate that is later used to coated the edge indirectly) use the same types of seals. They include air (travels through the edges) and vacuum seals (which create a channel over the edges).
Drying time:
Draper drying machines can take between 5 and 120 minutes, depending on the material, temperature, and moisture. The exact time is determined by the air blower speed. Other machines have similar or even shorter drying times.
Temperature and power:
Temperature range:
Mid-range and higher-end machines can generally operate within a temperature range of 100℃ and 200℃. The temperature is set based on the type of leather and the primers.
Power requirements:
The power requirements depend on the type of the machine. A bench-top machine could be powered by 1,500 W of electricity, while a more extensive floor-standing machine uses around 6,500 W. Standalone machines use more power, up to 22,000 W.
A leather edge coating machine is expensive and should be maintained to prevent breakdowns and extend its lifespan. Some maintenance tasks are simple and do not require special skills or tools, for example, routine inspections. Other tasks are complicated and demand specialist knowledge.
Maintenance requirements are specified in the machine's manual. The manual provides the manufacturer's instructions, including the maintenance schedule. The schedule lists the routine inspections and the maintenance tasks completed. Notes on the tools required to complete each task are also provided.
Generally, operators should regularly inspect the machine and parts to look for signs of wear and tear, damage, or leaks. The belts, seals, and gaskets should be examined closely to look for any fraying or tearing. Components should be adjusted to ensure they are appropriately fit. Any loose components should be tightened, and the air pressure settings should be checked and calibrated as necessary. The coatings should be cleaned up. If there is a build-up of any foreign material, concentrated cleaning solutions should be used to clean them up.
