Claim:
1. A plant for manufacturing compresses having a cooling effect, comprising at least a main dry compress manufacturing unit comprising: a device for longitudinally moving a water-permeable textile lower sheet which is continuously unwound and delivered flat to a delivery end of said unit, underneath an absorbent particle powder feed hopper; a device for depositing successive doses of said powder in grooves formed longitudinally in said moving lower sheet by reversible heat deformation; a device for covering the moving lower sheet and powder with an upper sheet which is continuously unwound and delivered flat at the same time as said lower sheet to said delivery end of said unit to form an assembly; a device for isolating adjacent powder-filled grooves from each other transversely by longitudinally welding said upper sheet and lower sheet together along intervals between said adjacent grooves; a device for forming successive compartments in each groove, each containing a dose of said absorbent particle powder, by welding said sheets together along transverse weld lines across the width of the moving assembly; and a device for cutting the resulting moving assembly into successive dry compresses by moving the assembly between rollers, one of which has a blade, thereby producing successive dry compresses, each containing doses of absorbent particles enclosed tight in separate grooves.
