    摘要： A heat seal bar attachment device for a bag making apparatus is used to detachably attach a heat seal bar to a heater. A rod with an attachment head is inserted through the heater. A support supports the heater. A slider is accommodated in a guide recess of the support to be slidable together with the rod, and receives one end of the rod. A biasing member is disposed between the heater and the slider to bias the slider towards a bottom surface of the guide recess. A fluid supply unit is configured to supply fluid to the guide recess and stop supplying the fluid. The fluid supply unit is configured to supply the fluid to the guide recess to slide the slider together with the rod against the biasing member.

    摘要： It is an object of the present application to prevent a waste from being attached to the upper blade or the lower blade of a crosscut device reliably.
    A waste removing device 5 for a bag making apparatus is attached to the bag making apparatus which makes a plastic bag from plastic films 10, 11. The apparatus comprises a crosscut device 31 configured to crosscut the plastic films 10, 11. The crosscut device 31 comprises upper and lower blades 310, 311. The waste removing device 5 comprises a scraper portion 50 configured to sweep a waste W from the upper or lower blade 310, 311. The waste W is made from the plastic films 10, 11 with the crosscut device 31.

    摘要： A welding method heats a surface to be welded of a continuous strip member with a laser beam. The welding method pressurizes the strip member and a continuous film to weld the surface to the film, when or after heating the surface with the laser beam. The welding method preheats the surface before heating the surface with the laser beam. A welding device includes a heat device having an infrared light source disposed to extend along a feed path for the strip member. The heat device is configured to irradiate the surface with infrared light to heat the surface with infrared light. The welding device includes a pressure device configured to pressurize the strip member and the film to weld the surface to the film.

    摘要： Punched and incised portions can be formed properly, in which it is not necessary to replace an anvil depending on a type of a sheet material. A punching unit 51 comprises: a punching blade 50 for punching a first panel material 11, a second panel material 12, an open tape and a mounting base portion so as to form a punching portion; a incising portion 51 for incising the second panel material 12 and the mounting base portion disposed on the open tape so as to form a incising portion; and an adjusting portion 54 for adjusting a first gap 56 in a punching direction 5Z between edges 50A and 51A of the punching and incising blades 50 and 51.

    摘要： Successively making plastic bags each of which includes an end surface provided with a spout, comprising
    forming a first folded portion (7) along a first fold line (6) extending adjacent to one side edge of a first web of panel material (1);
    thereafter, superposing a second web of panel material (2) with the first web of panel material (1) on a side opposite to the first folded portion such that one side edge protrudes beyond the first fold line;
    thereafter, feeding the first and second webs along a horizontal plane;
    forming apertures (15) in the protruding side edge by means of an aperture forming device (14);
    inserting spouts (5) into the apertures by means of a spout inserting device (16);
    heat sealing the spouts to the second web by means of a spout seal device (17);
    thereafter, folding the second web along a second fold line (19) extending between the spouts and the first fold line when the first and second webs are fed for forming a second folded portion (3) superposed with the first folded portion, the spouts being turned over with the second folded portion; and
    heat sealing the superposed portions with each other and the second folded portion (3) and the second web with each other about the spouts by means of a circumferential seal device (20, 24).

    摘要： A plastic film punching apparatus is improved to make a waste (13) removed reliably. In the apparatus, a plastic film (1) is sandwiched between and punched by male and female blades (2) and (3). The female blade (3) has opposite surfaces which are first and second surfaces (4) and (5). The plastic film (1) generates a waste (13) which is pushed by the male blade (2) to protrude from the second surface (5). A vacuum source (8) and an opening (9) cooperate with each other to suck air through the opening (9) and generate airflow (14) within the tubular cover (7), the waste (13) being removed by the airflow (14).
