A nonwoven hospital sponge material has been provided comprising a layered fabric having an inner core of a substantially hydrophilic material disposed adjacent at least one outer or surface layer or between a pair of outer layers of a substantially hydrophobic material, said sponge material being bonded by passing the material through rolls engraved in a pattern of lands and grooves in such a way...

A make-ready device for making a thread end ready preparatory to tying it to another thread end in a thread tying device, the make-ready device including s hollow body open at opposite ends thereof and traversible by a gas flow for receiving the thread end therein so as to at least partly stretch and parallelize the fibers of the thread end and cleanse them of short fibers, as well as for retainin...

The present invention concerns a machine for breaking up bulk material by means of a cutting mechanism which comprises at least two shafts driven contradirectionally and equipped with cutting tools, and is supplied with the material which is to be broken up via a chute or hopper leading to the working area of the cutting tools, the drive to the cutting mechanism being switchable into reverse drive...

A winding mandrel for a ball winding machine has umbrella stretchers at its forward portion on which yarn is wound. The front end of the mandrel is provided with a plurality of radial channels open on frontal edged for receiving a yarn and retaining means movable with respect to the front end to occlude at least one of the radial channels to hold the yarn in the channel.

A safety ski binding comprises a holding device which is mounted in an articulated manner on a main piece and is tensioned by a movable tensioning device which is of the type of a knee-joint device and comprises two movable parts as well as an elastic system, the binding comprising a stop system which allows the boot to be clamped tightly in the binding simply by putting the binding on.

The invention relates to a safety ski binding, having a holding device which is mounted in an articulated manner on a main piece and is tensioned by a movable knee-joint tensioning device which comprises two movable parts which are connected to one another in an articulated manner at a connection point, and one of which is connected to the main piece at a hooking-in point, while the other is conne...

In order to avoid producing any secondary waste in the production of a fibrous and a granular material from household, agricultural, forestry waste, organic waste of the manufacturing and/or service industries, the primary waste first undergoes an opening treatment in an opening unit and then, after removal of any metallic components by magnetic separation units, is divided into three fractions. S...
