Abstract

Abstract This invention relates to an apparatus for bonding textile fabrics or similar sheet material by utilizing heat-activatable adhesives of the thermoplastic or thermosetting type, the apparatus being of the type including a pair of relatively movable presser bars between which adhesively coated lapped portions of the sheets are subjected to heat and pressure during a bonding operation. A retractible locating mechanism is provided adjacent the lowermost, stationary presser bar for accurately positioning an edge portion of a first sheet relative to a second sheet carried by the upper, movable presser bar. Releasable clamping means secure the second sheet to the movable presser bar, and the clamping means are preferably of an adjustable nature for securing different mixed ones of the second sheets to the movable presser bar. The movable presser bar also carries means for heat-pressure securing a third sheet, such as a label, to the second sheet which may, for example, be the waistband of a garment, prior to bonding the waistband to the sheet supported by the stationary presser bar, the latter sheet being, for example, the ''''developed'''' length of a pair of trousers, shorts or similar garments. Piston-cylinder mechanisms are provided for exerting the necessary pressure during a bonding operation, and means are provided for preventing the operative positioning of the pistoncylinder mechanisms relative to the movable presser bar and the actuation thereof when an operator''s hand or other obstructions are positioned between the presser bars. In a preferred form of the invention each of the various means and mechanisms heretofore described is controlled by and under the influence of a fluid circuit system.
