Abstract: A machine for wrapping articles is disclosed which forms a sheath of the wrapping material, which can be paper or shrink wrap, around each article. The machine comprises a main endless conveyor including a plurality of article supporting platforms which rise in step-like array towards a sealing section, travel horizontally through the sealing section, and then descend in step-like array. Anvils and heat-sealing bars on endless conveyors are guided from above and below into the gaps between the platforms to form the sheaths. The anvils, bars, and platforms move continuously, parallel to one another, and at the same speed through the sealing section. An arrangement which pulls back the wrapping material is provided to ensure that each sheath is a relatively tight fit. The upper conveyor carrying the anvils can lift away from the main conveyor should an article become wedged in the machine.

Abstract translation: 公开了一种用于包装物品的机器，其围绕每个物品形成包装材料的护套，其可以是纸张或收缩包裹物。 该机器包括一个主环形输送机，它包括多个物品支撑平台，它们以朝向密封部分的阶梯状阵列的方式升高，水平地穿过密封部分，然后以阶梯状阵列下降。 环形输送机上的砧座和热封条从上下引导到平台之间的间隙中以形成护套。 砧座，杆和平台彼此平行地移动，并以相同的速度通过密封部分移动。 提供拉回包装材料的布置以确保每个护套是相对紧密配合的。 承载砧座的上部输送带可以在主体输送机上离开主体输送机，如果物品楔入机器中。
