What the LMH035 cold pad batch range does
The LMH035 is a padding range for cold pad batch pretreatment of pure cotton fabric. The cloth goes through a pad bath, is squeezed to a set pick-up, and is then wound on a roll and left to react at room temperature.
Runda lists it mainly for padding in pretreatment, where the pad liquor thickens the size on the cloth and does the desizing. Bleaching and similar steps follow the same pad and batch pattern.
Cold pad batch saves steam and water against a hot continuous range. The trade-off is time. The roll sits for hours, so you need floor space and a roll-turning stand.

Typical cold pad batch values (reference values per industry standards)
| Item | Reference value | Note |
|---|---|---|
| Pick-up after squeezing | 70 to 100% on cotton woven | Set by the mangle pressure and fabric |
| Batching time | 4 to 24 h | Shorter for enzyme desizing, longer for bleaching or dyeing |
| Batching temperature | Room temperature, rolls turned slowly | Cover the roll to prevent drying at the edges |
| Pad bath temperature | 20 to 40 °C | Depends on the chemistry |

Selection points for the LMH035
Process fit. Cold pad batch suits cotton woven in lots of a few thousand metres up. Very small lots tie up a roll for hours and cost more per metre.
Width and roll size. Match working width to your widest greige and plan the roll diameter the A-frame exit can hold.
Speed and pick-up. 30 to 75 m/min is the working range. Uniform pick-up across the width matters more than top speed, so check mangle pressure and roll crown.
Floor space. Reserve space for batching stands. A roll sits for hours, so count rolls in flight, not only the machine footprint.
Downstream. Plan the washing range that follows. Cold pad batch only starts the reaction; the cloth still needs rinsing.
Typical applications of the LMH035 Cold Bleaching Range
- Enzyme desizing of cotton woven fabric
- Cold pad batch bleaching with hydrogen peroxide
- Cold pad batch reactive dyeing, with a suitable dye and alkali system
- Pretreatment ahead of a continuous washing range
Configuration options
- Pad trough with level control and chemical dosing (optional)
- Roll turning stand for batching (optional)
- Rubber or metal squeeze rolls (optional, per liquor)
- Entry accumulator for continuous running (optional)
Items marked optional are available on request. The final configuration is confirmed on the quotation.
LMH035 Cold Bleaching Range: frequently asked questions
Why use cold pad batch instead of a hot continuous range?
It uses little steam, saves water and gives low fabric tension. The cost is batching time, so it suits plants with space and mid to long lots.
How long does the roll sit?
Typical times run from 4 to 24 h depending on enzyme, peroxide or dye system. Your chemical supplier sets the final time.
What fabrics does it handle?
Runda lists pure cotton for this model. Blends depend on the chemistry; ask us before ordering.
Does it include the washing unit?
The published data covers the padding range. The washing line is a separate machine; we can quote both together.
