Bag sealer

An apparatus for binding an article with adhesive tape comprising:

• a housing having a cavity bounded by a front wall and a rear wall for accommodating a supply of adhesive material;
• means for guiding said adhesive material;
• mans for transporting an article at least along and against said adhesive material;
• rotatable star wheel, said star wheel having a number of substantially radial recesses disposed at mutually equal angular distances, and a peripheral surface, said star wheel mounted to said housing between two mutually registered open channels in the front wall and rear wall of said housing, such that an article for binding may be transported from the top to the bottom of the housing through said channels;
• a tilt member, said tilt member located adjacent said star wheel and extending between said channels, said tilt member having an actuating part movably pivotal about a pivot axis towards and away from said star wheel, said tilt member having a spring means for releasably urging said tilt member to a rest position from which the tilt member may be pivoted to an active position;
• cutting means actuable by a through-fed article engaging said actuating part for cutting said adhesive material as said article is passed through said channels, said cutting means affixed to said tilt member and adjacent to said star wheel such that said cutting means is in an extreme cutting position for cutting said adhesive material when said tilt member is pivoted to an active position by a through-fed article engaging said actuating part;
• stop means configured to limit the displacement of said tilt member such that said cutting means is out of engagement with said peripheral surface of said star wheel when said tilt member is pivoted to an active position, said stop means comprising a first stopper cam affixed to said tilt member and at least one second stopper cam affixed to said star wheel, such that the first and second stopper cams contact as said tilt member is pivoted to an active position to limit the displacement of the tilt member and cutting means;
• wherein said adhesive material is guided over the star wheel and said star wheel is positioned such that an article for binding engages in a recess opening of said star wheel, the opening of the recess being situated between the channels such that as the star wheel is rotated, the article is bound with the adhesive material and the actuating part of said tilt member releases the tilt member from a rest position to an active position such that the cutting means engages the adhesive material and said stop means limits the displacements of the cutting means such that the cutting means is out of engagement with said peripheral surface of said star wheel as said adhesive material binds the article.
