Definitions

  • FIG. 3 F164 JNVENTOR.
  • Coffee-brewing filter bags are formed of filtering paper by adhering together two elongated webs of filtering paper along alternately oppositely inclined lines with the more closely adjacent ends of the inclined lines interconnected by stripes of adhesive parallel to the length of the webs. Coffee bags are then cut out along lines that follow the middle of the lines of adhesive, with an open end cut out along a circular are opposite the bottom edge of the bag. The bag blanks are thus cut from the webs in the pattern shown in the drawings to minimize waste of material.
  • This invention relates to a filtering bag for brewing coffee and has for its object to form such bag in a manner which renders possible simple production with a minimum of consumption of paper.
  • the invention also relates to a manner of making the bag.
  • the filtering bag according to the invention is characterized in that it consists of two layers of filtering paper which are pasted together along the bottom and two lateral margins of the bag.
  • the manner of making the bag is characterized by providing one of two layers of filtering paper with an adhesive along stripes corresponding to the bottom and lateral margins of the bag, pasting the layers together, punching or cutting the bag out from the layers so that the bag will consist of the two layers which are pasted together along the bottom and the lateral margins.
  • Mass production is possible by providing one or both layers with adhesive stripes defining a plurality of bags such that the bottom portion of every second bag lies at one margin of the layers and the bottom portions of the other bags lie at an opposite margin of the layers.
  • the adhesive stripes for the various bag blanks can be placed close to each other at the lateral margins so that the paper can be effectively utilized.
  • the layer consists of paper webs to which adhesive stripes can be applied corresponding to a plurality of rows of bag blanks.
  • the stripes of each row can be arranged such that the bottom edge of every second bag blank faces one longitudinal edge of the webs and that the bottom edges of the other blanks face the other longitudinal edge.
  • Four or eight or even more rows can be arranged along the two webs.
  • the bag blanks can be punched out from the layer webs which are put together and connected to each other along the stripes, where the punched cuts are placed in the middle of each adhesive stripe or midway between two parallel adhesive stripes and further along an arcuate line defining the mouth of the bag.
  • FIG. 1 is a plan view of a pair of paper webs pasted together along stripes such that the stripes contain a plurality of rows of bag blanks to ⁇ be punched out from the webs.
  • FIG. 2 shows how the bag blanks can be punched out so as to reduce the wastage to a minimum.
  • FIGS. 3 and 4 are perspective views of the finished bag.
  • FIG. 1 two webs of filtering paper are assumed to be placed in superimposed positions and pasted together along stripes which define figures substantially in the form of a V.
  • FIG- URES 1, 2, 3 and 4 Four rows of FIG- URES 1, 2, 3 and 4 are illustrated, but any number of rows may be chosen.
  • V-shaped figures are arranged such that the vertex of the V corresponding to the bottom of the bag of every second figure faces one longitudinal side edge 5 of the webs and that the vertices of the V:s of the other figures are facing the other side edge 6.
  • Adhesive stripes 7, 8 located at the lateral margins of a bag extend on the bag blank parallel and close to adjacent corresponding adhesive stripes 9, 10 on the adjacent bag blanks in the same row.
  • the chain-dotted line 11 denotes the outline of a bag blank.
  • the bag blank is to be punched out from the webs along said outline.
  • the punching line 11 extends midway between the adhesive stripes 7, 9 and the adhesive stripes 8, 10 and passes along the adhesive stripe at the bottom of the bag blank.
  • the upper edge of the bag blank is defined by a punching line which is a curve 12 in the form of an arc of a circle. At this place there is of course no adhesive stripe because the bag is to be open.
  • FIG. 2 illustrates two rows 1, 2 of figures to be punched out.
  • the row 1 comprises a pair of adjacent figures A and B.
  • a figure to be punched out is denoted at C.
  • the figure C in the row 2 is located opposite the figure A in the row 1 and has its mouth line edge 12 directed toward the bottom edge line 14 of the figure A.
  • the distance between the rows at end 2 should be as small as possible. The distance is defined by the minimum distance a. between the lines 12 and 14 that is allowed by the punching tool, and consideration has to be taken to obtaining neat edge lines.
  • any mouth edge line 12 in a row such as 2 and the confronting mouth edge lines of the figures in the row 1, the last-named lines being located on either side of the figure in the row 1 that registers with the said figure in the row 2.
  • the ideal configuration with regard to the wastage of material between the rows is obtained if the distance a is equal to the distance b.
  • the wastage of material between the rows 1 and 2 is represented by a hatched surface 15 and the wastage of material at the edge 5 is represented by a hatched surface 16.
  • a still better utilization can be obtained by a certain other scheme of the outline of the bag blank, viz., if the mouth edge lines 12 are straight insead of arcuate and located such as to coincide with the edge of the web.
  • the bottom edge line 14 may also be straight and parallel to the edge of the web.
  • a straight punching line 12 for the mouth edge results in a bag having concave lips because the lateral margins are not parallel to each other whereas the punching line 12 in the form of an arc of a circle and results in a bag lip which in the finished bag lies in a single plane. For this reason a punching line 12 in the form of an arc of a circle is preferred.
  • the machine may be constructed so as to be able simultaneously to punch a plurality of pairs of webs pasted together.
  • the various webs are suitably marked so that it is possible to make sure that the adhesive stripes of a web are registering with the adhesive stripes of the other webs or Web.
  • FIG. 1 an adhesive stripe is shown for each bag blank, and the punching line 11 extends between parallel adhesive stripes 7, 9 and 8, 10 elongated at the lateral margins of adjacent bag blanks.
  • the punching line 11 may be applied with the punching line extending midway thereof.
