Abstract: The present invention relates to a surface treatment process for ceramic mechanical seal rings of pumps, of the type comprising a first cold-moulding process of the ceramic powders in a suitable die and a second sintering process of the ring, characterised in that the moulding process is performed with a punch with head provided with a plurality of punctiform micro-projections; another object of the present invention is the seal ring obtained with the said process.

Abstract: The device for cutting continuous modules comprises means for feeding said continuous modules to cutting means arranged to cut said continuous modules in order to form a plurality of sheets of predetermined dimensions. The cutting means comprise two or more cutting units arranged to cut the continuous modules to simultaneously form two or more sheets of predetermined dimensions. The process for cutting continuous modules consists of feeding the continuous modules to cutting means and cutting the continuous modules to form a plurality of sheets of predetermined dimensions. Advantageously a plurality of transverse cuts are made simultaneously, to simultaneously form two or more sheets of predetermined dimensions.

Abstract: A sheet handling device comprising a cutting member (1) for cutting at least one sheet (A) produced by industrial printers to obtain two sheets (B) there from, and a control member (3) for distributing the sheets obtained in this manner by directing them towards suitable post-print document processing devices.

Abstract: The device (1) for feeding sheets to a finishing line for documents formed from these sheets comprises, for supporting a pack (4) of sheets, a table (5) which cooperates with sheet extraction means (6) for transferring a sheet, to a filter (8) defining a slot (9), and to means (11) for its expulsion towards the finishing line. The device comprises means (13) for adjusting the thickness of the slot (9) and/or means (15) for controlling the force exerted by the extraction means (6). The process for feeding sheets to a finishing line comprises the steps of extracting a sheet from a pack (4), passing the sheet (7) through a slot (9) which allows one sheet at a time to pass, and expelling the sheet (7) towards the finishing line. The thickness of the slot (9) and/or the extraction force exerted on each sheet extracted from the pack (4) are automatically adjusted.

Abstract: A protection for a sports shoe, particularly for a golf shoe, comprising a sheath that can be applied to a tip of the shoe and is provided with removable retention elements to prevent disengagement from the shoe.

Abstract: A device for automatically binding booklets (5) each presenting a variable number of sheets (4), comprising assembler means (40) for grouping the sheets of each booklet and presenting at least two separate means (80, 81) for feeding the sheets of each booklet towards a common gathering station (82), means (89, 41) for moving each booklet from said station to said binding means (33), and means (3) for measuring the thickness of each booklet (5) to be automatically bound, the binding means (33) forming for each booklet, on the basis of the measured thickness of the booklet to be bound, a personalized covering element for at least part of the visible faces and for an outer edge of the booklet.

Abstract: A device for automatically binding booklets (5) comprising a variable number of sheets (4), including means (3) for measuring the thickness (S) of each booklet (5) to be bound, and a binding line (33) arranged to automatically fix, at least about that edge (34) of said booklet (5) in which the sheets are secured together and about a portion (28) of the first (4A) and last sheet of the booklet, a cover element (8) comprising a first part (21C) arranged to adhere to said edge (34), and a second (21A) and third part (21B) arranged to adhere respectively to at least said portions (28) of the first and last sheet; said line comprising means (9, 13) arranged to generate, on the basis of the measured thickness of the booklet to be bound, for each booklet, a particular cover element (8) having dimensions and creasing lines (L1-L4) such that said three parts (21A-C) of the cover element perfectly follow said edge and said portions of the first and last sheet.

Abstract: A device for arranging documents printed on continuous strips, of the type using at least two continuous strips each printed in at least two columns. The device comprises conveyor belts for advancing the strips, rotating blades for longitudinally cutting the strips, at least one additional blade for transversely cutting at least a part of the strips, a movable wall for directing the documents, obtained from the strips, to at least one waiting and selective sorting station for the documents and to a transit section, and a collecting station for the documents originating from the waiting station and transit section and comprising a conveyor belt for selectively sorting the documents to obtain the required arrangement.
