Class 120(2) A thread tensioning device in which the thread is deflected. to a greater or lesser extent from its straight path by means of a carrier which is under initial spring loading and which is pivotable about a transverse axis relatively to a fixed thread guide, is characterized by the combination of the following features: (a) that the spring initially loading the pivotable carrier is so arranged in space in relation to the pivot that when the carrier varies its position owing to a change in the thread tension, the consequent change in the spring tension produced thereby is nullified by a corresponding change in the radius of action of the spring relative to the pivot so that the torque exerted by the spring. remains constant or becomes greater with a weakening of the thread tension; and (b) that a plurality of thread eyelets is. arranged symmetrically on the carrier on both sides of the pivot, said carrier thus being mounted in equilibrium. As shown,. the device comprises a casing 1 having mounted therein thread eyelets 3, disposed on either side of a pivot 2, and also an inlet eye 4 and an outlet eye 5 all arranged in the same straight line. On the pivot 2' is mounted a carrier having pairs of eyes. 9, 10 and 11 symmetrically spaced on either side of the pivot 2. Fastened to the carrier at 19 and to the casing 1 at 21 is a spring 20 which tends to move the carrier into the position shown so that the thread 6 is deflected from its straight line course.. The attachments of the spring 20 are so arranged that the torque which it exerts on the carrier remains substantially constant or preferably decreases with a decreased deflection of the carrier due to a rise in the thread tension.

In a method of bundling stacks of sheets banding material is successively introduced as a loop between each adjacent two stacks or across the face of one stack against which the next is to be formed until the loop projects over the adjacent slack edges, the projecting portion of the loop being so folded over the two adjacent stacks or the next stack while being formed that it contacts the free end of the neighbouring loop or loops, the thus folded loop portion then being connected to the neighbouring loop or loops and its outer portion severed adjacent the joints. In one embodiment a loop plunger 6 draws material 10 from a reel 9 to form a loop 15 held back on refraction of the plunger by a holder 7. Adhesive is applied by a device 19. As sheets 13 from a feed device 1 are pushed behind retaining springs 5 by a slide 3 the stack 14 so formed is compressed by previous stacks. A brush 8 folds the previous loop 16 into contact with loop 15, and they are interconnected in known manner by hand or machine and severed between the joints. The plunger 6 acts when a predetermined number of sheets has been assembled. The table 2, side walls 4 (Fig. 2), slide 3 and the plunger stroke are adjustable for different-sized sheets. In a second arrangement (Fig. 4) the loops are connected in the centre of a stack face. The loops may be interconnected by welding, knotting or clamping. A separate stack compressing device may be provided, and the brush 8 may be replaced by a plunger.

Abstract: 944,915. Labelling apparatus. KLEENSTIK PRODUCTS Inc. July 28, 1961 [July 28, 1960], No. 27547/61. Heading B8F. Relates to apparatus for stripping pressuresensitive adhesive labels from a backing strip and applying the stripped labels to articles by utilizing a blast of high pressure air or gas. The backing strip 10, Fig. 3, with labels attached are fed from a reel 13 around the forward edge of a stripping bar 17 and via feed rollers 18, 19 to a take-up reel 20. The abrupt change in direction of the backing strip at the edge of the bar 17 strips each label from the strip and presents it to a grid located at the bottom of a housing 31, where it is retained by light suction applied continuously by a fan. At this point a microswitch operated by the label causes the strip feed to cease and when the article is in position beneath the grid, it operates a further microswitch which causes blasts of air to be directed through nozzles 42, 43, 44, Fig. 6, against the label. These blasts override the suction applied by the fan and blow the label on to the article with sufficient force to cause adhesion thereto.
