摘要:
A sheet material advancing and cutting apparatus for incrementally advancing the cut end of a supply of terry cloth sheet material (11) past a cutting blade (66), drawing out the supply of material to its cutting position, and cutting the material along laterally extending napless bands (26) in the material. The apparatus includes a sheet material advancing mechanism (13) for engaging the sheet material and pushing the cut end of the material across the cutting station (14). A material draw out assembly (16) includes a draw out bar (81) which moves downwardly into engagement with the leading edge of the material and pulls the material into its cutting position. The draw out bar (81) is pivoted by cylinder (111) if necessary to stretch the side of the material that is behind in its movement toward the cutting station, causing the following napless band to be straightened.
摘要:
Segments (35) of flexible sheet material (30) are continuously and progressively conveyed through a series of work stations (34, 40). Each segment (35) of the sheet material (30) is advanced along its length from a first work station (34) to a second work station (40) at a first rate of movement. The leading edge portion (14) of the segment (35) is advanced through the second work station (40) at a rate of movement slower than the first rate of movement. A portion of the segment (35) trailing the leading edge (14) is temporarily accumulated at a position between the first and second work stations (34, 40) until the segment (35) is advanced through the second work station (40).

摘要:
Du tissu (30) pour drap est prélevé d'un rouleau d'approvisionnement (32) et coupé en segments (35) par un dispositif de coupe (36). Les segments sont déplacés rapidement, et parallèlement par rapport à leurs bords coupés, vers un premier poste de couture (40) à fonctionnement plus lent, où des bandes élastiques sont cousues aux bords latéraux des segments. La partie arrière à déplacement rapide du segment (35) de tissu est temporairement accumulée au poste d'accumulation (39), puis progressivement alimentée, à une vitesse inférieure, à travers le premier poste de couture (40). Les bords latéraux sont pliés de façon à se placer au-dessus de la partie principale du tissu dans un poste de pliage (42). Des machines à coudre (164 et 165) sont déplacées vers l'intérieur du parcours de couture afin de couper et de coudre simultanément des coins en diagonale au niveau des bords avant et arrière des segments, les machines à coudre pivotant de façon à faire face au mouvement relatif du tissu pour drap, puis les bandes élastiques (21) et les coins enlevés (25) sont tirés hors de l'ouvrage produit par l'intermédiaire d'un système d'aspiration (186).
摘要:
Transport plate (28) is moved downwardly into engagement with work product (25) and the plate (28) moves the work product to the edge finisher, such as sewing head (12) (Fig. 3). When the first edge (68) covers the first sensor (61), the transport plate (28) begins its movement from right to left (Fig. 4) so as to move the first edge (28) through the edge finisher, and the edge is finished as with an overedge stitch. When the second edge (69) uncovers the second sensor (62), the transport plate (28) rotates around an axis of rotation (75) (Fig. 5), causing the work product (25) to be rotated about the same axis of rotation (75) and the edge finisher forms the overedge stitch about the curved path until the second edge (69) covers first sensor (61), whereupon the linear right to left movement is resumed (Fig. 7).
