A portable folded wiper dispensing system for dispensing flexible sheets from a stack of sheets. The system includes a refillable apparatus and a stack of sheets. The refillable apparatus is composed of: 1) a relatively flat, flexible base devoid of dispensing slots, the flexible base being adapted to resiliently fold along a fold axis; and 2) a flexible cover defining an opening aligned in parallel relation to the fold axis of the flexible base such that the flexible cover is attached to said f...

Plastic bag are stacked as they are received from a bag making machine by a radial arm transfer wheel whose suction arms engage the bags by transferring edges thereof and with the ends of the arms so that the bags are pressed onto needles of needle bars on a needle bar basket. The needle bars are rotated, with the bags suspending therefrom the spindling position through an intermediate position into a smoothing and removal position in which the hanging stack is lifted to a horizontal orientation...

A method and machine for forming a case with polygonal section from a blank of sheet material. There is an assembly of panels. The assembly of panels is wound about a mandrel with polygonal section. The tongue is fixed to the free edge of the endmost panel. The flaps situated on the same side of the panels are folded. The flaps thus folded are fixed together.

The milling cutter comprises a body (1) having two indentations (4,5) each presenting a housing (4',5') the body of which makes with the longitudinal axis of the body a helix angle which is not equal to zero. In each housing a cutting insert (6,7) is removably fixed which comprises a tip portion emerging on the frontal face (9) of the body and a main cutting edge extending beyond and along the external lateral rim of the indentation. The position and the shape of this insert are such that the ra...

A face milling cutter for holding a plurality of cemented tool bits for rotation about an axis and an associated method utilize a body of material defining a shank portion securable within a rotatable spindle of a machine tool for rotation about an axis and an insert-accepting body portion within which the tool bits are supported. The insert-accepting body portion is generally cylindrically in shape and joined to the shank portion so that the longitudinal axis of the body portion coincides with ...

A lathe apparatus for machining flat, circular disk-shaped recording media, for example, audio, video or ROM compact disks, for the purpose of improving their surface quality and their dimensional stability is provided which comprises a driven lathe spindle (7), a vacuum chuck (8) for holding the recording medium or substrate (15, 15') to be machined, a carriage (9) for holding and guiding the tool (5), and magazines (14) for holding the machined and unmachined substrates. A robot (10) provided ...

The device comprises a box-like body inside which two shoes are slideable and are actuated in opposition. A shoe is compsed of a plate which has a guiding opening for a gib of the other shoe. Brackets are rigidly and protrudingly associated with the top of the gib and with the lower end of the plate and bear respective jaws which are adapted, in jaw closure position, to define a guiding duct for a bar and, in opening position, a passage for the bar-pusher. The opposite actuation of the shoes is ...

A system of hand-held lathe tool assemblies especially for executing large scale deep and/or hollow work efficiently and rapidly while minimizing operator fatigue. Tool working portions may be integral with their carriers or holders or may be selectively connected to them by means of a conventional chuck or collet. The butt portions of very long lathe tool assemblies permit the turner to apply forewarm and/or upper body to the tool and gain sufficient leverage to work comfortably and hence with ...

A corner forming unit of a package forming machine which employs an H-shaped guide over which the packaging material passes after it has been longitudinally sealed. A pair of rollers outside of the tube of material forms the edges of the packaging material into the H-shaped guide to form the corners of the material from which individual filled rectangular packages will be formed.

A tray forming machine comprising an infeed station for accepting a blank of corrugated plastic, and a transfer mechanism which automatically conveys the blank along a plane into a blank receiving station between a tray forming ram and a forming tool frame. The tray forming ram moves downward along a vertical path carrying the blank through the forming tool frame, during which the blank is folded into a generally upright tray configuration by a series of vertically displaced side and end forming...
