Publication number: 20090263546Abstract: A single-lobe filter bag for infusion products comprises a length (2) of filter material forming a chamber (3) containing a charge (4) of the infusion product. The length (2) comprises: a first closed top end (5) formed by a first join (S1) between two first end edges of the length (2); a second closed bottom end (7) and two sides (8, 9) connecting the two ends (5, 7) of the length (2); the two sides (8, 9) connecting the first and second edges (5, 7) are at least partly folded onto each other to form a fold towards the inside of the chamber (3) and the second bottom end (7) of the filter bag (1) is closed by second join (S2) designed to form a rigid flat bottom surface (11) of the filter bag (1) such as to define a stable base, with a substantially triangular cross section, for supporting the filter bag (1).Type: ApplicationFiled: June 11, 2007Publication date: October 22, 2009Applicant: IMA FLAVOUR S.R.L.Inventors: Dario Rea, Rodolfo Caroli, Sauro Rivola

Patent number: 5588643Abstract: Tubular blanks, from which containers to be filled and closed are set up, are stacked in flat condition inside a magazine (3), so that they rest on supporting bars. A back edge of the lowermost blank of the stack is engaged by a pair of lugs mounted on a belt conveyor situated under the magazine, so that the lugs protrude upwards beyond a rest plane defined by the supporting bars. The lowermost blank is stripped by passing it through a passage delimited by the supporting bars and stops situated above the supporting bars, and aimed at stopping blanks of the stack situated above the blank just withdrawn. The belt conveyor carries the withdrawn blank through following working stations.Type: GrantFiled: February 6, 1995Date of Patent: December 31, 1996Assignee: I.M.A. Industria Macchine Automatiche S.p.A.Inventors: Roberto Tagliaferri, Rodolfo Caroli
