摘要:
A method and apparatus (10) is provided for the formation of a tablet (21) from tableting feedstock (20). An elongate die is provided which has a cavity (16) defined by an inner wall (18). A pair of die punches (22, 24) are insertably positioned within the cavity. The die punches include opposed facing surfaces (30) for supporting therebetween tableting feedstock. The die punch are relatively movable within the cavity to a tablet forming position to compress the feedstock into a tablet. The tablet forming positions defined by the facing die punch surfaces are spaced apart a sufficient distance so as to maintain the formed tablet in contact with the inner wall of the cavity so as to retain the tablet within the cavity upon removal of the die punches.

A method and apparatus provides for the formation of compression dosage units from tableting feedstock (36). A feedstock dossiter (10) is provided including an open ended chamber (26) for insertion into a reservoir containing the tableting feedstock. The dossiter includes a movable die punch (30) which is movable within the chamber between at least two positions. A first position away from the open end (24) of the chamber provides for the collection of a preselected volume of tableting feedstock from the reservoir. The die punch is movable to a second position which effects formation of the tablet within the accumulation chamber. The dossiter may be used with a fixed die punch to form the tablet.
摘要:
An apparatus and method for continuously making chopped amorphous fibers that uses an air transport system. The apparatus includes a source of floss (12), a duct (20) for transporting the floss while it is entrained in a stream of gaseous carrier medium, a chopper (28) for chopping the floss, and a separator. In a preferred embodiment, the floss is chopped while it is entrained in the stream of gaseous carrier medium using a rotating ring chopper, and the chopped floss is subsequently separated using a cyclone separator (26).
摘要:
The present invention provides a method and apparatus (10) for forming a compression dosage unit such as a tablet. The method of the present invention includes dispensing a premeasured volume of tableting feedstock (30) into a product tray (25). The feedstock is compacted into a tablet within the product tray. The product tray may be further packaged for distribution and sale. The apparatus of the present invention includes a dossiter (39) for dispensing the premeasured volume of feedstock into the product tray from a reservoir (40). A die is insertable into the product tray to form the tablet therein. The dossiter may be used to form the tablets within the product tray.
