Disclosed is a welding machine for synthetic resins. The welding machine for synthetic resins performs welding of fabrics using ultrasonic waves and through preheating sufficient not to burn off a coating solution on the surfaces of the fabrics using hot air so as to achieve rapid and firm welding due to concentrated molecular decomposition and melting on the bonding surface between the fabrics, allows both an ultrasonic horn and a welding wheel to be rotated vertically so as to achieve rapid and stable entry of the fabrics and welding of the fabrics while preventing the fabrics from slipping, and achieves stable welding of various fabrics through adjustment of pressing force of the welding wheel depending on the thickness or the material of the fabrics, etc.

The present invention relates to a pouch-shaped battery sealing apparatus including a stopper capable of adjusting a thickness after sealing in a process of sealing the outer edge of a battery case made of a laminate sheet by applying heat and pressure thereto when a pouch-shaped battery is manufactured and a pouch-shaped battery sealing method using the same.

A head seal device of a bag making apparatus includes a pair of seal units configured to face each other in a facing direction. Each of the seal units includes a heat seal member and a heater. The heat seal device includes an adjustment unit configured to move the first seal unit in a width direction of continuous sheet panels, and to move the second seal unit in the width direction of the sheet panels in accordance with movement of the first seal unit in the width direction.

A disclosed apparatus for forming a sealing portion for folding a secondary battery pouch includes: first and second pressing bars disposed to face each other with a sealing portion for folding therebetween to apply pressure for flattening the sealing portion for folding that is defined by the edge of a secondary battery pouch for sealing an electrode assembly accommodated therein; first and second pressing surfaces provided at the first and second pressing bars, respectively, and disposed to face the sealing portion for folding; and a forming protrusion formed on the first pressing surface and configured to form a folding guide line on the sealing portion for folding by pressure applied by the first and second pressing bars.

The invention relates to a hand-guided device (10) for setting a setting element (12) in a component. The device comprises a handle (14) for holding the device, a carriage (34), which can be moved in relation to the handle and which bears a rotatably supported drive shaft (46), at one end of which a holder for the setting element is formed, a force accumulator (44), which is arranged between the handle and the carriage and which serves to store a defined advancing force, with which the force limiter can be loaded by means of a relative motion between the handle and the carriage, and a force limiter (64) for limiting the advancing force stored in the force accumulator. The force accumulator is designed to apply the stored advancing force to the setting element by means of the carriage. The invention further relates to a method for manually setting a setting element by means of said device.
