Claims
- 1. Method for forming a pattern of compression in a material for absorbent products, which comprises the steps of:providing at least one compression structure having an outer compression surface and including press means projecting from said outer compression surface; said press means having moisture emitting holes; locally compressing the material with said press means to form at least one local pattern of compression; and locally supplying moisture to the material via said moisture emitting holes only in a patterned region corresponding to the pattern of compression during said compressing step.
- 2. The method according to claim 1, wherein additional moisture is supplied to said material via a counter-roller or counter-surface.
- 3. The method according to claim 2, wherein said counter-roller or counter-surface is heated.
- 4. The method according to claim 1, wherein said press means is heated.
- 5. The method according to claim 1, further comprising the step of cooling said pattern of compression.
- 6. Apparatus for forming a pattern of compression in a material for absorbent products, which comprises:at least one compression structure having an outer compression surface and including press means projecting from said outer compression surface of said compression structure; said press means structured and arranged to form at least one local pattern of compression; said press means having moisture emitting holes therein which are operatively connectable to a source of moistening fluid, said moisture emitting holes, in use, emitting moisture only to a patterned region corresponding to the pattern of compression.
- 7. The apparatus according to claim 6, further comprising a counter-surface or counter-roller; said counter-surface or counter-roller comprising moisture emitting means.
- 8. The apparatus according to claim 6, further comprising valve means for controlling the supply of a fluid to said moisture emitting holes.
- 9. The apparatus according to claim 6, wherein said at least one compression structure is a roller or stamping plate.
- 10. The apparatus according to claim 6, further comprising heater means for heating said press means.
- 11. The apparatus according to claim 6, further comprising heater means for heating moisture emitted by said moisture emitting holes.
- 12. The apparatus according to claim 6, further comprising cooling means for cooling said local pattern of compression.
- 13. Apparatus for forming a pattern of compression in a material for absorbent products, which comprises:at least one compression structure having an outer compression surface and including press means projecting from said outer compression surface of said compression structure; said press means structured and arranged to form at least one local pattern of compression; said press means having moisture emitting holes therein which are operatively connectable to a source of moistening fluid, said moisture emitting holes, in use, emitting moisture only to a patterned region corresponding to the pattern of compression, and at least one of counter-surface and counter-roller means, which comprise moisture emitting means.
- 14. The apparatus according to claim 13, further comprising heater means for heating said press means.
- 15. The apparatus according to claim 13, further comprising heater means for heating moisture emitted by said moisture emitting holes.
- 16. The apparatus according to claim 13, further comprising cooling means for cooling said local pattern of compression.
